Bob Rusk

Robert "Bob" Rusk is the main antagonist of the 1966 novel Goodbye Picadilly, Farewell Leicester Square and its 1972 film adaptation Frenzy, directed by Alfred Hitchcock. In the film, he is played by Barry Foster.

Beneath his charming, "ladies man" exterior, Rusk is a woman-hating psychopath with violent sexual tastes. He is also a serial killer who rapes dozens of young women and strangles them with neckties. When he murders his friend Richard Blaney's ex-wife Brenda, suspicion falls on Blaney. Rusk also murders Blaney's girlfriend Barbara and disposes of her body in a lorry filled with potatoes. When he discovers that Barbara grabbed his tie pin while fighting for her life, Rusk hops onto the moving lorry and breaks her fingers, which have gone stiff with rigor mortis, so he can get it back. He then hops off the lorry unnoticed.

When the police start looking for Blaney, Rusk offers to hide him in his flat - and then calls the police. Blaney figures out that Rusk is the murderer, but too late - he is found guilty of Rusk's crimes and sentenced to life in prison. Believing himself to be untouchable, Rusk celebrates his freedom by killing another woman. When he goes out to get a crate to dispose of the body, however, Blaney and Inspector Oxford, the chief investigator on the case, have arrived at his flat. Rusk is then then arrested and imprisoned for life.
