Query: A novel that makes you wonder what will happen next.

This novel was well written and it keeps you wondering what will happen next. Its full of murders, suspense, and mistaken identities. This is one book that should be read by all. Keeping with the tough guy image of the Film Noire genre with the example of Lieutenant Degarmo the first time he meets Detective Marlowe "If I have to get tough, fellow, you'll know it". I recomend this easy to read and enjoyable book fully and give it 4 stars.
