Summary & analysis
Holmes takes a case he loathes: Milverton, the king of blackmailers, is squeezing a bride-to-be over old letters. Negotiation fails against a man who enjoys ruin, so Holmes — astonishingly — proposes burglary, and dons a mask to do it.
There is little deduction and much reconnaissance: Holmes courts Milverton's housemaid for the layout, times the household, and takes Watson cracking into the study by night. The 'investigation' is a heist, and the moral cost is the point.
Hidden behind a curtain, the pair watch another victim — a wronged woman — shoot Milverton dead and grind her heel into his face; Holmes lets her go and burns the letters. He declines to identify her to Lestrade the next day: some justice the law is not fit to touch.
Deeper reading
The detective as burglar
Charles Augustus Milverton is morally the boldest story in the canon: Holmes, faced with the king of blackmailers, becomes a housebreaker, and then declines to prevent — or report — the man\'s murder by one of his victims. Doyle lets his hero step outside the law entirely, judging that some evils forfeit its protection. It is the clearest statement of Holmes as private moral arbiter rather than agent of the state.
A villain of pure cold
Milverton himself is one of the great creations — soft, smiling, and utterly without heat, a man who trades in ruin as a business. Holmes\'s revulsion is unusually personal, and the story\'s refusal to punish his killer is a deliberate provocation. It remains one of the most discussed of all the tales for exactly that reason.
