What is the name of the serial killer in Hitchcock's 'Frenzy'?

The serial killer in Alfred Hitchcock’s *Frenzy* is Bob Rusk.

Rusk appears at first as a familiar Covent Garden figure who runs a fruit-and-vegetable stall and knows Richard Blaney. Behind that ordinary public identity, however, he is the murderer nicknamed the “Necktie Murderer.” He rapes and strangles women with neckties, while deliberately directing suspicion toward Blaney.

Rusk’s knowledge of Blaney’s troubles makes the frame-up especially effective. After killing Brenda Blaney, he manipulates evidence and tips off the police, helping send the innocent Richard to trial. The truth emerges when Inspector Oxford reexamines the case and connects Rusk to the murders.

A common mistake is choosing Norman Bates, another Hitchcock killer, or Bruno Antony from *Strangers on a Train*. Bob Rusk belongs specifically to *Frenzy*, Hitchcock’s 1972 return to a contemporary London crime story and his penultimate feature film.
