List of Harper's Island characters

This is a list of fictional characters in the television series Harper's Island.

Abby Mills
(Portrayed by Elaine Cassidy)

Abby Mills is Henry Dunn's best friend. She left the island seven years ago when her father, Sheriff Mills, sent her away after her mother was killed by John Wakefield, a scene she had witnessed. When she is back on the island, she attempts to reconcile with her father and her former boyfriend Jimmy. She usually hangs out with the groomsmen. Abby never wanted to return to the island after her father sent her away after the 2001 massacre, but still does so because of Henry and Trish's wedding. She is also good friends with Trish, especially after she helps her cope after her father's death. She is smart, strong, and brave, determined to protect her friends and stop Wakefield and finish the job that her father did not finish. She's initially suspected to be Wakefield's child based on an entry in his prison diary. That, along with the thought that the Sheriff is responsible for the murder and J.D.'s last words that it's all about her, causes others to partly blame her, until Madison tells the truth that the Sheriff is not the killer. It's eventually revealed that Henry is her half-brother, and is Wakefield's son and is working with his father to commit the murders. After Shea and Madison escape, Henry turns on Wakefield and kidnaps Abby and Jimmy, planning to frame Jimmy as Wakefield's accomplice and create his childhood fantasy life with Abby. She manages to engineer their escape by pretending to give in and slipping Jimmy a lock pick through a kiss before turning on Henry, and stabs Henry through the chest protecting herself and Jimmy. Henry's last words to Abby were that he loved her.

SURVIVAL – Abby, along with Jimmy, gets rescued by coast guards and taken to the mainland.

KILLS – Henry Dunn.

Henry James Dunn
(Portrayed by Christopher Gorham) He's Abby's long-time best friend. His parents' deaths several years earlier left Uncle Marty and J.D. as his only living relatives. In the second to last episode, he's revealed to be Wakefield's son, protégé (he was responsible for numerous deaths in Seattle, as practice), and accomplice, and Abby's half-brother. His motive is revealed to be his obsession with Abby; he loves her in his own twisted way, and is killing everyone around them in order to create a childhood fantasy life with her as he remembers Abby's wish that they could stay on the island forever, just the two of them. For most of the first part of the series, Henry deals with several problems such as proving himself to Trish's disapproving father, dealing with his suspicions about Hunter, and helping his friends do something about the blooded money they found. Henry acts as the survivors' unofficial leader, but has, in actuality, orchestrated the whole situation with his father and committed some of the murders. He turns on his father to protect Abby then kidnaps her and Jimmy and fakes their three deaths, planning to force Jimmy to sign a confession so Abby and he can live alone together on the island. Despite her reaction to his confession and previous escape attempt, he believes she shares his dream and takes her to say goodbye to Jimmy, which she does in order to slip Jimmy a lock pick. He lashes out at her when she rejects him, but Jimmy, who managed to free himself, tackles him off a cliff to protect Abby.

Trish loves her father and sister very much, as well as Henry, unlike her father. Trish is consistently pursued by her ex-lover Hunter (with the help of her father), but she shuns him away. Henry even sets a test by sending a fake rendezvous to Trish from "Hunter" but he sighs with witnesses Trish back out from the meeting.

She very beautiful, but also intelligent and crafty, which is seen after she tricks the man who found (and refuses to give back) Cal's supposed engagement ring for her. At first her relationship with her boyfriend Cal seems shallow; she's an outgoing flirt and has attracted the interest of both Sully and Marty. However, later events make it clear that Chloe's feelings for Cal are genuine, proving that behind her bombshell exterior lies a woman who is searching for romance and true love. She, along with Cal, Beth and Sully tries to leave the island but Cal convinces her to stay because Madison's life will be at stake if they leave.

It was later revealed that when Abby saw her mother get killed by Wakefield, it was Jimmy who distracted him so that Abby could get away. Abby and Jimmy rekindle their relationship shortly before the wedding guests are supposed to be sent home. In Episode 10, Jimmy is almost killed when the docks explode, but is spared because of Sheriff Mills' agreement with Wakefield to trade his life for Jimmy's, and is again spared during the Cannery massacre.

Thomas Wellington
(Portrayed by Richard Burgi)

Thomas Wellington is Trish and Shea's father. He's also Katherine's husband. He's a conservative real estate mogul. He only wants the best for his daughter; but as far as he's concerned that doesn't involve marrying Henry Dunn. Wellington is accustomed to getting his way, and plans on stopping this wedding at all costs. He's also the only character that would have ever suspected Henry as the killer; in Episode 5, "Thwack", he admitted that he didn't trust Henry based on "gut instinct".

DEATH – In Episode 5, during the wedding rehearsal, Maggie tells Wellington to step up as if to light the unity candle, and then asks for someone to turn off the lights. When Abby flicks the switch it also triggers a mechanism that releases a headspade hidden in chandelier, causing it to fall on Thomas' head and split it in two down to the neck. His death makes everyone realize what is going on in the island. In Episode 12, Trish learns (before her death) that Henry killed her father.

Appearances: Episodes 1–5

Killed by Henry Dunn.

J.D. Dunn
(Portrayed by Dean Chekvala)

J.D. Dunn is Henry's adoptive brother. He's a dark and brooding loner with tattoos all over his body that speak more to his true nature than he ever lets on in conversation. Being the only brother of the groom should have made him a lock for “best man,” but J.D.’s barely a guest at the wedding and wouldn’t mind just missing it all together. His childish antics make Henry’s life more difficult, and sometimes there’s a malevolence in them that makes everyone wonder if J.D. has some secret endgame. He relates to a local girl named Kelly and has sex with her before her death. He also has a huge conflict with Shane that almost killed him. He's arrested as a murder suspect in Episode 8, and tells the Sheriff where to find Cole Harkin, who he was helping track the copycat killer. He escapes later the same episode when the police station is attacked.

DEATH – In the end of Episode 8, J.D. is found by Abby hidden behind some barrels on the docks, bleeding profusely from an abdominal wound. Abby asks him who did this to him, but J.D. can only say that the murders are "all about you" before he dies. In the next episode, his body is taken to the clinic by Jimmy and Henry. It's revealed in the finale that Henry killed him on the docks, and that Abby almost caught him in the act. In Episode 13, Sully learns (before his death) that Henry killed JD and others.

Appearances: Episodes 1–3, 5–9, 10 (picture)

Killed by Henry Dunn.

Christopher "Sully" Sullivan
(Portrayed by Matt Barr)

Chris is Henry's best man. All of his friends call him "Sully". He's a fun-loving frat boy at heart whose good buddies live vicariously through his many sexual escapades. He's been Henry's best male friend since middle school. It's questionable if he's at the wedding more for Henry's benefit or for the bachelor party and bridesmaids, particularly when he gets an eyeful of Chloe. He is referred as the "team player" of his gang (consisting of him, Danny, Malcolm, Booth, and occasionally Abby and Beth). He attempts to attract Chloe into being with him instead of being with Cal, even forcing Cal to switch teams with him. He unintentionally forgets to save Cal in Episode 2, who gets caught in a rope trap. Cal, along with Chloe, then takes revenge on Sully by throwing feathers on his honey-coated body (he was at the spa), which was so humiliating that even his own gang laughed at the joke. Although he initially wants to leave immediately despite the threat to Madison's life, in Episode 10, he volunteers to go with Cal to find a sailboat so everyone can escape the island, and when Cal is shot in the process, he takes him to the clinic and, under Cal's direction, manages to remove the bullet and save Cal's life. The two form an unlikely friendship, and Sully realizes how much Cal and Chloe love each other. He later teams with Danny in an effort to save Chloe, and ambushes and shoots Wakefield while Danny acts as bait, but the others choose not to kill Wakefield. Sully says that it is a "big mistake". When Trish finds a boathouse, Sully stays in the boathouse to man the radio, and puts Shea and Madison on a small boat after Wakefield's escape, but chooses to stay behind to help his friends. He later goes with Henry to look for Trish, intending to find her and the others before heading to the marina to meet the Coast Guard.

DEATH – In Episode 13, Sully is searching for Trish with Henry when Henry starts to act suspicious. When Henry admits to killing Trish and JD, Sully at first thinks it's a sick joke but soon catches on. Still, he can't bring himself to shoot Henry, even as he lists whom he killed, until he laughs about killing Malcolm. Sully attempts to shoot him, but Henry reveals he unloaded the gun, and then flips the gun around to hit Henry. Henry then tells him that John Wakefield is behind him. Sully asks Henry how stupid he thinks he is, and Wakefield replies, "Pretty stupid." Henry stabs the distracted Sully in the back, fatally wounding him, but before he dies Henry tells him, "You never should've dogged Trish," referring to an earlier episode where Sully admitted to trying to sleep with Trish when she and Henry were broken up in college.

Appearances – Episodes 1–13

Killed by Henry Dunn.

Marty Dunn
(Portrayed by Harry Hamlin)

Uncle Marty is a surrogate father to Henry – the only family besides J.D. that he has at the wedding. Uncle Marty loves being the center of attention; he started partying sometime in the 1970s and just never stopped. But behind his blithe demeanor is someone who cares deeply for Henry and would do anything to protect him. And behind that is a guy who pops pills when no one is looking while toting around a bag stuffed with bundles of cash and a gun. In "Sigh," Henry reveals that Marty wanted to use the money to invest in Malcolm's brewery.

DEATH – In the pilot episode, Marty walks over a footbridge when a few floorboards give way and he falls halfway, becoming stuck. He then hears someone under him and asks them to help. The sound of slicing is heard and Marty attempts to shoot through the bridge, but fails to hit his attacker and is cut in half.

Appearances: Episode 1

Killed by John Wakefield.

Hunter Jennings
(Portrayed by Victor Webster)

Hunter Jennings was Trish's ex-boyfriend from college. He's from a family as affluent as the Wellingtons. He's exciting and passionate. He's also selfish and unreliable, which is why Trish broke up with him. But now that she's getting married, Hunter has shown up (hired by Mr. Wellington) on the island even though he's not invited, hoping to convince Trish that he's the one she should be marrying. A deleted scene on the series DVD has Katherine showing Thomas a file on Hunter, revealing the man has been disowned from his family for his thieving ways, making Thomas realize he may not be a good match for Trish after all.

DEATH – In Episode 3, Hunter is headed off to the mainland with a bag of money that's revealed to be Uncle Marty's in Episode 13. Soon, the boat stops and Hunter struggles to open the base of the boat, with a shotgun attached and triggered to shoot him. The shotgun shoots his face off and his body is found in Episode 4 by the groomsmen. It's revealed in Episode 13 that Henry killed Hunter Jennings.

Shea Allen
(Portrayed by Gina Holden)

Shea Allen is Trish's big sister and the Maid of Honor. From the outside, she appears to have it all – a great husband, a beautiful daughter, and all the money in the world. But nothing is as it seems. There are problems in her marriage and her daughter Madison is acting out. Trish later reveals that she found her husband cheating on her with Katherine. The stress of keeping up appearances has Shea trapped in a life that may seem like every woman's dream, but she never really wanted for herself. With the exception of a few locals, Shea and her daughter, along with Abby and Jimmy, are the only survivors of the Harper's Island murders.

SURVIVAL – Shea and her daughter escape the island on a small motor boat, leaving the others behind. Although Shea wants to stay so she could help, Sully manages to convince her by telling her that her main priority had to be keeping Madison safe.

Appearances – Episodes 1–13

Richard Allen
(Portrayed by David Lewis)

Richard is Shea's husband, a guy who married into the Wellington family and business and lives every day with that fact hanging over his head. Henry sees Richard as an example of what not to become – a meek subordinate who has completely broken under the thumb of Mr. Wellington. It is implied that he worked for Mr. Wellington before he met Shea, and won his favor by being successful and making sure that his wife and daughter are happy. Richard keeps his severe contempt for Mr. Wellington under wraps, but is already in the process of taking revenge on the man who has made his life so miserable. Despite his fault, he still insists that he loves Shea, and that his affair is just to humiliate Mr. Wellington. In Episode 3, it's revealed that he was having an affair with Katherine Wellington. Trish sees him with Katherine and reveals their betrayal to her father during an argument, but Mr. Wellington decides to do nothing until after Trish's wedding.

DEATH – In Episode 6, Richard is impaled by a harpoon and pulled out of sight. Henry, Abby and Katherine find his corpse tied to a tree in Episode 8, with the harpoon still in him. In the final episode, Henry tells Sully he harpooned Richard. The final thing he said was "...Madison."

Appearances: Episodes 1–6, 8

Killed by Henry Dunn.

Madison Allen
(Portrayed by Cassandra Sawtell)

Madison is Shea and Richard's daughter. She's cute, sweet, and sometimes, horribly spooky. Many kids enjoy mischief but Madison might enjoy it a little too much. She has a tendency to say things that indicate she has a better idea about what's happening on Harper's Island than the adults do. Madison was kidnapped by Wakefield through episodes 8 and 9, though she tells Abby that it was the Sheriff who abducted her. In episode 10 she tells Trish that she lied, claiming that Wakefield told her that if she didn't, her mother would "disappear" like her father. It is also Madison who reveals that Wakefield is not working alone. Madison later tells her mother and Trish that she first met Wakefield, her "new friend", the day they arrived on the island. Both Madison & her mother survived the series and left the island.

SURVIVAL – Madison escaped with her mother on a boat in episode 13 with the help of Christopher 'Sully' Sullivan. Later on, they are both at the police station. Madison gets sent off with Agent Perez so that Shea and the other Agent can talk privately. Just as Madison goes out of the room, she says "He's going to tell you everyone else is dead, isn't he?"

Appearances – Episodes 1–13

Katherine Wellington
(Portrayed by Claudette Mink)

Katherine is the very definition of a trophy wife; a woman closer in age to her stepdaughters than her husband. Trish used to resent her, but Shea had always tolerated her because she makes their dad happy. But considering Katherine's secret dark desires, that might not be for long. In Episode 3, it's revealed that she was having an affair with Richard Allen. Still, Katherine seem to genuinely care for her step-family and tells them that what she did is not meant to hurt anyone, because she does love her husband. According to producers, a subplot was meant to be included that Thomas had lost all his money through a bad business deal and that it was Katherine who was paying for the entire wedding, but she allowed Thomas to pretend he was doing it so he did not lose face in front of his daughters. The storyline was dropped due to time constraints.

DEATH – In the end of Episode 9, Shane tells Katherine (who he thought was alive) that the group had found Madison, and then notices the blood seeping through the sheets on the chair. It is then revealed that she was stabbed in the back with pruning shears. In Episode 10, Shane shows Henry Katherine's corpse and tells him that she was still warm when he checks for a pulse, meaning that she was killed very recently. In the final episode, it's revealed that Henry killed Katherine while everyone was running around looking for Madison.

Appearances: Episodes 1–6, 8–10

Killed by Henry Dunn.

Danny Brooks
(Portrayed by Brandon Jay McLaren)

Danny is a groomsman and one of Henry's best friends from college. He's the sensitive guy in the group. He's thoughtful and always wants to do the right thing. Danny feels things deeply, and when he senses injustice, he can't walk away, but has to try to make things right. He is mainly the closest friend of Sully, but is still close to Malcolm and Booth, and likes Cal. He is kind enough to attract many friends, which Sully envies. In Episode 12, he acts as bait for Wakefield so Sully can ambush and shoot him. Wakefield even admits that he put up a good fight, and that he did not embarrass himself.

DEATH – In Episode 12, Danny attempts to fight Wakefield so that Shea and Madison can escape the town jail. Although he puts up a good fight, Wakefield manages to grab him and impale him through the right eye with a memo holder.

Malcolm Ross
(Portrayed by Chris Gauthier)

Malcolm Ross is a groomsman. He's a big, boisterous guy who not only brings his own beer to a party, but he brews it himself. Malcolm is trying to start up a business to mass-produce his microbrew, Sacred Turtle. Even though his friends are very supportive emotionally, he lacks the funds to finance his endeavor. His inability to raise capital has put a great deal of stress on Malcolm, and made him desperate enough to do things his friends would never suspect. When their group decides to make Booth hide the money, he follows him to convince to take it with them, but Booth accidentally shoots his leg. Malcolm tries to save Booth but after his death, he buries him, takes the money and does not tell his friends what happened. Among his friends, Booth is the one he is closest to.

DEATH – In Episode 7, Malcolm is burning money when he is yanked away and hacked to bits; his limbs and head are then thrown into a furnace (in a deleted scene that was considered "not suitable for television"). Cal later finds his skull in Episode 8, but doesn't know who the skull belongs to, though he reassures everyone it isn't Madisons'.

Killed by Henry Dunn.

Joel Booth
(Portrayed by Sean Rogerson)

Joel is a groomsman. Everyone calls him by his surname, Booth. He's a loyal friend who lacks some of the social graces of the other groomsmen. His hypochondria amuses his friends to no end, particularly his sea-sickness. He can be very jumpy and panicky, although his decisions are usually for the best. When the groomsmen found Uncle Marty's money, they decided to hide it until they can bring it to the police after the wedding. Unable to decide who would hide it, they had a draw, resulting Booth as the one tasked to hide the bag. Malcolm follows him and he shoots his own leg. As Malcolm tries to call for help, Booth begs not to be left alone, and eventually dies on Malcolm's hands.

He has a particular distaste for Henry Dunn's brother, J.D., especially after J.D. starts flirting with his ex-girlfriend, Kelly. Shane's got a short temper and a history of violence, which makes him capable of just about anything. When Kelly dies, he believes that it is JD's fault and he kidnaps him, planning to kill him by hanging. Abby rescues JD telling Shane that she believes Kelly's statement that John Wakefield is alive and most likely killed her. Shane reveals that he is blaming himself for Kelly's death.

Shane only got out after he promises to tell Abby where the Sheriff went.

DEATH – In Episode 11, Shane attempts to fight Wakefield with a pocket knife, covering the girls' escape through the Cannery bathroom.

She's struggled with depression and suicide attempts and a secret belief that John Wakefield is still alive and coming back for her. Kelly used to date Shane, who is very bitter over their break-up. Kelly also finds companionship with JD which only worsens the rivalry between the two boys. When Kelly expresses her desire to finally leave the island and go to LA, Abby hesitates in allowing her to stay with her, but Abby eventually tells her that she can be her roommate until she gets her own place.

She seems to be Abby's confidant and best girl friend, helping her with her potential relationship with Jimmy. As Abby returns, Nikki is the one who updates her with what is going on in the island. A good friend of Kelly's, she is the one to find her body, but is otherwise nearly completely excluded from major events. She manages to walk into the Cannery unimpeded, which convinces Maggie the killer isn't after locals, and gives the others her keys so Sully and Cal can use her car to go get the sailboat. Nikki shares a kiss with Sully before he leaves with Cal, but any potential relationship ends with her death at Wakefield's hands.

DEATH – In episode 11, Nikki is the first to react when Wakefield breaks into the Cannery, immediately going for the gun behind the bar.

Sheriff Mills reminds him that John Wakefield is dead, but Doctor Campbell replies that someone is doing, "one hell of a job imitating him." He reminds Sheriff Mills that the head spade, used in several killings, was Wakefield's signature weapon.

John Wakefield
(Portrayed by Callum Keith Rennie)

John Wakefield was the perpetrator of a killing spree in 2001 on Harper's Island and the series' main antagonist. He originally killed six and wounded five in various locations on the island. The victims were hacked with a head-spade, burned in the Marina explosion or hanged from the Tree of Woe. The surviving victims all sustained severe burns. Wakefield grew up in Tacoma, Washington. He was a fisherman that frequented the waters off of Alaska and Washington.

Wakefield came to Harper's Island in the 1980s after tracking down his ex-girlfriend Sarah Mills who had fled from him because he was abusive. After trying to get her to leave with him Sarah's boyfriend Sheriff Charlie Mills had several of his Deputies try to get him to leave by scaring him. He attacked one of the men, Cole Harkin and cut him pretty badly. He was arrested for one count of attempted murder of a police officer and was given a life sentence. He was held at a maximum security prison in upstate Washington. Wakefield was released in 2001 for "good behavior", after completing only 17 years of his sentence. Wakefield soon returned to Harper's Island, where he went on a murderous rampage.

After the murders, it's believed that Sheriff Charlie Mills shot and killed Wakefield, but recent photographs that match up almost identically to Wakefield's figure suggest otherwise. In Episode 10, John Wakefield is revealed to be alive and on the island and he also kills Maggie Krell and Sheriff Mills and tells Abby that she "looks just like her mother". In Episode 11, he goes to the Cannery and kills Nikki and Shane. He later takes Chloe hostage and after Cal found her, he kills Cal by stabbing him, leading Chloe to kill herself.

Wakefield's motives remain unclear throughout most of the series. While many townsfolk remember Wakefield as wanting to get revenge on the Sheriff for wrongfully imprisoning him, it's revealed that he had a romantic relationship with Abby's mother, and when Chloe asks, Wakefield states that he "almost died for a woman" like her. Wakefield's wrath is fueled by the fact that Sarah gave up their son Henry for adoption, but kept Abby. Wakefield is familiar with the weapons the survivors are carrying, and, knowing they contain very limited ammunition, gives his victims a chance to shoot him as a long-range stationary target before either retreating or killing them. In Episode 12, it's revealed that Wakefield is Henry's biological father. Wakefield appears in Episodes 5–6 of Harper's Globe.

DEATH – In Episode 13, Abby is stuck in the middle of a stand-off between her, Henry and Wakefield. Wakefield believes Henry will finish her off, but is betrayed by his son as he gets stabbed instead.
