Play It Again — Stephen Humphrey Bogart

R.J. Brooks long ago left behind the flash and glitter of Tinseltown for a life of bruised knuckles and cheap sex as a "matrimonial detective" in New York City. But he finds himself facing agonizing ghosts form his past when a house dick finds his beautiful and celebrated mother murdered in a Manhattan love nest. To solve this case he needs both his street smarts and his Hollywood connections. One way or another he has to find the killer...

Because when your mother is murdered, you have to do something about it. It doesn't matter if you liked her or not. She was your mother and you have to do something. Even if it means risking your own life.
