To Kiss, or Kill
Bok av Day Keene
You never can tell what a big, tough Polish boy will do when he finds a nude blonde in his bathroom. Especially if he is a heavyweight fighter who was born back of the yards, is married to a million dollars, and has a psychiatric record. He might do a number of things. He might tell her to get out. He might yell for his wife. He might blow what's left of his top. He might even do what Barney Mandell did, come to his addled senses...
