Pools Bottles and Deaths

Three books of the later CD Grimes.
Bottleneck
Mrs. Bellows, at the community center, is murdered. It leads to an international kiddie porn ring. CD is not about to let anything go unresolved on this one! He has three young kids of his own!

Dead File
A note in an old file. A boat that blew up. Land deals and scams. Deaths for insurance – and one wasn't dead. A Caribbean island. Sordid people. A puzzle within a puzzle within a puzzle.

Pool Party
A gun found in an old chest in an ex-bawdyhouse. A ten year old murder, now this one. How was it connected, and what did Len Stewart have to do with it?
