Mr Croup is one of the bad guys in Neil Gaiman's novel Neverwhere. He is the one that talks, whereas Mr Vandemar is the one that does most of the violence. He is incredibly vicious and cold-blooded, and makes Hannibal Lecter look like a shoplifter. He is one of the most amusing evil characters in print. In Terry Pratchett's The Truth, the equivalent of Mr Croup is Mr Pin. There is some evidence to suggest that Mr Croup is basically a personified fox.
