"The Problem of Thor Bridge" is a Sherlock Holmes murder mystery by Arthur Conan Doyle, which appears in the collection The Casebook of Sherlock Holmes. The story was previously published in the Strand Magazine and Hearst's International Magazine in 1922.
Synopsis
Neil Gibson, the Gold King, approaches Holmes to investigate the murder of his wife Maria in order to clear his children's governess, Grace Dunbar, of the crime. Holmes compels Gibson to admit his attraction to Dunbar and his dislike of his wife.
Maria Gibson was found lying in a pool of blood on Thor Bridge with a bullet through the head and note from the governess, agreeing to a meeting at that location, in her hand. A recently discharged pistol with one shot fired is found in Miss Dunbar's wardrobe. Holmes agrees to look at the situation in spite of the damning evidence.
From the outset, Holmes observes some rather odd things about the case. How could Miss Dunbar so coolly and rationally have planned and carried out the murder and then carelessly tossed the murder weapon into her wardrobe? What was the strange chip on the underside of the bridge's stone ballustrade? Why was Mrs. Gibson clutching the note from Miss Dunbar when she died? If the murder weapon was one of a matched pair of pistols, why couldn't the other one be found in Mr. Gibson's collection?
Holmes uses his usual brilliant powers of deduction to solve the crime, and even demonstrates, using Watson's revolver, how it was perpetrated.
Connections to real-life events
In 2004 it was stated that the solution to the story may also explain the mysterious death of Richard Lancelyn Green, one of the foremost experts on Sherlock Holmes, who was found having been asphyxiated to death shortly after rediscovered papers of Conan Doyle were put up for auction.
According to David Stuart Davies, the inspiration for The Problem of Thor Bridge came from a real-life case in Germany, which the editor of the Strand Magazine had brought to Conan Doyle's attention.
