Charles Anthony Bruno (Strangers on a Train) is a wealthy man that meets Guy on a train from New York. It is easy to tell that his life of privilege has made him spoiled and slightly mental. He enjoys plotting murders in his spare time. He and Guy mention whom they'd like to both murder. Guy would like his ex-wife, Miriam, to die, while Bruno hates his father and wishes him dead. It is Bruno that offers to 'trade murders'. Guy will kill Bruno's father and Bruno will kill Miriam. Guy laughs everything off like it is a joke. Later, when Miriam is murdered, Bruno finds Guy to let him know that it was never a joke. He forces Guy to kill his father.
