A case of identity is a story by Arthur Conan Doyle, featuring the iconic detective Sherlock Holmes. The story revolves around a young woman named Mary Sutherland, who is desperate to find out the true identity of her fiancé, Mr. Hosmer Angel.
The story begins when Mary visits Sherlock Holmes, seeking his help in solving the mystery of her fiancé's identity. She tells him that Mr. Angel disappeared shortly before their wedding, and she has not heard from him since. She is convinced that he is hiding something from her, and wants to know the truth about who he really is.
Holmes agrees to take on the case and begins his investigation by questioning Mary about Mr. Angel's background and behavior. He discovers that Mr. Angel was very secretive about his past, and often made excuses to avoid talking about it. He also learns that Mr. Angel was in the habit of wearing a mask over his face, which Mary had thought was to protect himself from the cold.
As Holmes delves deeper into the case, he uncovers a number of clues that lead him to believe that Mr. Angel is not who he claims to be. He discovers that Mr. Angel's handwriting is identical to that of a man named Julius Handsaker, who was wanted by the police for embezzlement. He also finds out that Mr. Angel had a secret room in his house, which contained a number of documents that could potentially incriminate him.
Despite all of these clues, however, Holmes is still unable to prove that Mr. Angel is Julius Handsaker. He is eventually forced to conclude that the case of identity remains unsolved, and advises Mary to move on with her life.
Overall, "A Case of Identity" is a classic example of Sherlock Holmes's skills as a detective, as he uses his keen observation and deductive reasoning to solve a complex mystery. It is also a poignant story of love and betrayal, as Mary struggles to come to terms with the fact that her fiancé may not have been who he claimed to be.
