 His name was Pietro Venucci, from Naples he was, and he was one of the most notorious cutthroats in London. Venucci, the last link... He was connected with the old secret society of the Mafia, you see, and it's perfectly clear that he must have broken the rules in some way, so this fellow of the photograph is sent to kill him, or even perhaps the other way round. You know how fiendish they are in these vendetta things. At any rate, one is shadowing the other, there's a scuffle outside Harker's house, and in the struggle, Venucci gets his death wound.
