A year passes uneventfully. One night in late October, a servant girl witnesses Hyde beat a man to death with a heavy cane. The victim was MP Sir Danvers Carew, another of Utterson's clients, who was carrying a letter addressed to Utterson when he was killed. The police, who suspect Hyde, contact Utterson. He leads the officers to Hyde's apartment, feeling a sense of foreboding amid the eerie weather. (The morning is dark and wreathed in fog.) When they arrive at the apartment, the murderer has vanished, but they find half of the cane (described as being made of a strong wood but broken due to the beating) left behind a door. It is revealed to be one which Utterson himself gave to Jekyll. Shortly thereafter, Utterson again visits Jekyll, who now claims to have ended all relations with Hyde. Jekyll shows Utterson a note, allegedly written to Jekyll by Hyde, apologising for the trouble that he has caused him and saying goodbye. That night, however, Utterson's clerk, Mr. Guest, points out that Hyde's handwriting bears a remarkable similarity to Jekyll's own.
