He called her Red. She called him in from the cold. For one short moment in the big, hard city they were friends--and then the girl turned up dead. Mike Hammer will walk through walls to find out who she was and why she died, even if he doesn't like the answers he gets. Even if they are all about a seamy network of call-girls, blackmail, and hoods. Hammer owes something to Red, and he plans to make good-because in this town a friend is hard to find.
