Robert B. Parker's Fool's Paradise by Mike Lupica

They've found a dead man out at the lake.  He didn't drown, he was shot.  Jesse Stone was surprised he recognized him.  He'd been at the AA meeting he had attended a couple of towns away.  His name was Paul but that was all he knew about him.  He had no ID, no phone or anything else that could identify him.  What was he doing here and who had he come to see?

GP Putnam's Sons and Edelweiss allowed me to read this book for review (thank you).  It will be published September 8th.

It takes Jesse and several of his team members to find the man's identity.  Even then they don't know much because he was an orphan.  When they find the driver that dropped him off, they visit the house and asked them what he wanted.  They said he'd never called there...

The son there had been involved in an earlier crime in his life:  rape.  His father's money saved him from jail time.  Then one of the other boys involved turns up dead. 

Every time Jesse thinks he might be  getting close, he gets other information that takes him on another tangent.  He's a bulldog on the case and won't give up.  But if he's not careful, he could become the next victim...
