Doctor Thorne

Doctor Thorne is the third novel written by Anthony Trollope in his Chronicles of Barsetshire series, between Barchester Towers and Framley Parsonage. It was published by Chapman and Hall in London in 1858. The idea of the plot was suggested to Trollope by his brother Thomas. Though set in Barsetshire, Barchester and its residents take little part in the proceedings. The novel is mainly concerned with money and position.

Most of the narrative is based in the village of Greshamsbury, the seat of squire John Newbold Gresham, of an old and respected family, and his wife Lady Arabella, sister of the Earl de Courcy. They have a son and several daughters. The titular Doctor Thorne lives in the village with his niece Mary. She has grown up with the Gresham children and since the doctor is well acquainted with squire Gresham, Mary spends a great deal of time at Greshamsbury Hall. Mary's parentage is a mystery to the general public in the novel, but it is one of Trollope's most insistent principles to take the reader into his confidence. Since Mary Thorne has neither family background nor money, Lady Arabella discourages her from associating with her erstwhile playmates once they grow up. However, unknown to nearly everyone, Mary's maternal uncle, Roger Scatcherd, has risen from humble beginnings to great wealth.

Plot summary
When their father dies, Doctor Thomas Thorne and his younger brother Henry are left to provide for themselves. Thomas begins to establish a medical practice, while Henry seduces Mary Scatcherd, the sister of stonemason Roger Scatcherd. When Roger finds out that Mary has become pregnant, he kills Henry in a fight.

While her brother is in prison for the death, Mary gives birth to a girl. A former suitor offers to marry Mary and emigrate to America to start a new life, but not if she keeps the baby. Doctor Thorne persuades Mary to accept the offer, promising to raise his niece. He names her Mary Thorne, but, wishing neither to have her illegitimacy made public nor to have her associated with the uncouth Roger Scatcherd, he keeps her parentage secret. Mary Scatcherd tells her brother that the baby has died.

After his release from prison, Scatcherd rises quickly in the world, becoming extremely wealthy as an expert contractor. When he completes a seemingly impossible important project on time, he is made a baronet. Throughout his career, he entrusts his financial affairs to Doctor Thorne. When Thorne becomes the family doctor to the Greshams, he persuades Scatcherd to lend increasing sums to the head of the family, the local squire. Eventually, much of the Gresham estate is put up as collateral for these loans. Meanwhile, Mary Thorne grows up with the Gresham children and becomes a great favourite with the whole family.

As young adults, Mary and Frank Gresham — the only son and heir of the squire of Greshamsbury — fall in love. However, his parents need him to marry wealth; the squire has squandered much money on expensive and fruitless campaigns for a seat in Parliament and is grieved that he can leave little to his son. As Mary is penniless and of suspect birth, such a marriage is inconceivable to his mother and to her relatives, the aristocratic de Courcys. They wish Frank to marry the eccentric 30-year-old heiress Martha Dunstable instead. Frank reluctantly visits Courcy Castle in order to meet Miss Dunstable, and they become friends. He foolishly and playfully proposes, but she wisely demurs, knowing that he does not love her.

Sir Roger Scatcherd is a chronic drunkard, and Doctor Thorne tries in vain to get him to curtail his drinking. In his will, Scatcherd leaves the bulk of his estate to his only son, the dissolute Louis Philippe. However, he leaves Doctor Thorne in control of the inheritance until Louis Philippe reaches the age of 25. Should Louis die before then, Scatcherd stipulates that the estate goes to his sister Mary's eldest child. Thorne, knowing that Scatcherd is thinking of the children Mary had in America, is forced to divulge Mary's parentage to Scatcherd, but Scatcherd leaves the will unchanged.

Roger Scatcherd eventually dies of drink. The son proves just as much an alcoholic as the father, and his weaker constitution quickly brings him to the same end before he turns 25. After consulting with lawyers, Doctor Thorne confirms that his niece Mary is the heiress, now wealthier than even Miss Dunstable.

Unaware of these developments, the still resolute Frank finally persuades his doting father to consent to his marriage to Mary. When all is revealed, the rest of his relations heartily congratulate him.
