"A Study in Sherlock" is the fourth episode of the sixth season of the Murdoch Mysteries and the sixty-ninth episode of the series.

Whole Story Told In Words Edit

A bank carriage is robbed but the thieves' getaway ride is sabotaged by an apparent drunk, who loosens the horse's reins. One of the thieves then kills their driver before running off.

The next morning, as the corpse is found, a man claiming to be Sherlock Holmes introduces himself to Murdoch and Crabtree. The man is identified as David Kingsley, who suffers from a delusion of identity and insists that Professor Moriarty is behind the robbery. Attempts to coax him back to himself prove unsuccessful, even when they bring in Sir Arthur Conan Doyle to prove that Sherlock is fictional, as David gives a logical way for Sherlock to survive his last encounter with Moriarty.

Eventually, it is determined that the thieves were looking for a valuable diamond they've spent ten years searching for, about the same time David was committed. Murdoch is able to coax David back to himself by telling him that he witnessed his stepfather's murder, snapping him out of his delusions. David explains that his stepfather read to him many Sherlock Holmes stories and disguised one story about the Star of Tarsus as part of the series, as hint as to where the diamond was.

Murdoch and Brackenreid drop by David's old house to find David's uncle and accomplice searching through his old model boat in search of the diamond. Though the thieves surrender with Brackenreid holding a rifle. However, David also arrives, brandishing a pistol, determining to take vengeance for his stepfather's murder. Murdoch is able to convince him to stand down by encouraging him to return to his Sherlock persona, reminding him of Sherlock belief in justice and the rule of law.

The diamond is later found in the creek where David played with his boat, which David finds. Murdoch tells him that the Persian consulate is willing to pay a substantial sum for its recovery and asks who they should thank. David says they should thank Sherlock Holmes.
