Source-derived summary

"A Case of Identity" is one of the 56 short Sherlock Holmes stories written by Sir Arthur Conan Doyle and is the third story in The Adventures of Sherlock Holmes. It first appeared in The Strand Magazine in September 1891.

Plot

Mary Sutherland, a working-class girl who possesses a generous income as a result of a bequest from a relative, comes to Sherlock Holmes and Dr. Watson for help after her fiancé, Hosmer Angel, disappears on their wedding day. Angel, Holmes learns, was a quiet and secretive man who always wore a pair of tinted glasses, had a thick beard and mustache, and would not give Sutherland his address, insisting that she leave letters at the local post office instead. He would only meet her when her disapproving stepfather, James Windibank, was out of the country on business, and he wrote letters to her exclusively on a typewriter.

Holmes easily deduces that Windibank and Angel are the same person. Windibank knew that he could only benefit from his stepdaughter's income while she remained unmarried, and so he hatched a plan to keep her single indefinitely. As "Hosmer Angel", he successfully sought her hand; he then engineered Angel's disappearance before the marriage could take place. As he had hoped, Sutherland remained loyal to Angel, saying she could never love another.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “A Case of Identity”, the useful work is to connect “short story by Arthur Conan Doyle” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 3, 2026. The linked authority identifier is Q1151528. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1891.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
