Summary & analysis
Mary Sutherland — typist, small income of her own — is engaged to the shy, whisper-voiced Hosmer Angel, who makes her swear fidelity and then vanishes from the wedding cab between door and church.
Holmes needs no site visit: the courtship's odd constraints (letters typewritten down to the signature, meetings only when the stepfather is in France, tinted glasses and whiskers) are the evidence. Two letters — one to the firm, one to the missing man's description — settle it.
The typewriter convicts: its worn 'e' and damaged 'r' appear in both Hosmer's love letters and the stepfather's business correspondence. Windibank courted his own stepdaughter in disguise to bind her — and her income — to home forever; legally untouchable, he leaves with Holmes's whip nearly at his back.
Deeper reading
Detection without leaving the room
This slight, sharp story is a pure demonstration of armchair method: Holmes solves it entirely from the evidence carried in by the client and two letters, never visiting a scene. The typewriter\'s worn characters — a forerunner of real questioned-document analysis — do all the work. It is minor Holmes, but a clean showcase of the principle that the clues are usually already present if you know how to read them.
An uncomfortable ending
Doyle leaves the case morally unresolved: the villain is legally untouchable, and Holmes chooses not to shatter the deluded client\'s hope. The story quietly acknowledges the limits of the detective — that seeing the truth and being able to act on it are different things, a theme the canon returns to whenever the law and justice part ways.

Disguise & misdirection
Seeing through appearances built to deceive.
In this story: The disguise is dismantled by its constraints: everything about Hosmer Angel exists to be removable — whiskers, glasses, whisper — a man built to vanish.
