Plot summary
Who Killed the Robins Family? is a mystery novel in which all eight members of the Robins family are murdered or disappear throughout the story. The hardcover book provided no solutions to the murders. The books were also a contest where the person who provided the best answers to who, when, where, how, and why each murder happened won $10,000. The paperback version, released after the contest ended, revealed the answers to all the questions.

Most chapters revolved around the death of a Robins family member, though one chapter contained a murder and a disappearance, and two others involved a disappearance. Most chapters contained all the needed information to provide all five answers regarding each death, though some gave only a hint as to an answer. However, if properly understood, it only took a bit of minor research to obtain the complete answer.

The murders ranged from a classic locked-room puzzle to death by strangulation. The book also gives homage to several classic works of mystery and suspense.

As the book is a contest, liberties are taken with proper police investigation of the crimes, which would have resulted in an immediate solution. For example, when one family member is shot to death in a darkened room, nobody thinks to check for gunshot residue. In addition, while some murders have fit very neatly with the facts on a theoretical basis, the method of implementation has questionable realism.
