Nantucket Counterfeit: A Henry Kennis Mystery #5 by Steven Axelrod

Henry likes living on Nantucket.  It's quiet, there's not much crime, and everybody knows everybody else.  Then there's a murder...

Poisoned Pen Press and Net Galley let me read this book for review (thank you).  It will be published October 16th.

The first surprise is that the man who was killed was using a false name.  Just who is he?

The more people he visits with, the more suspects spring up.  It seems this fellow likes to sleep with wives and then blackmail the couple.  The more Kennis finds out about him, the more apparent it becomes that he's a slimeball.  Nobody feels bad that he's dead, but murder is still a crime.

Kennis centers on a suspect and then figures out he's been framed.  When he goes to brace the real killer, he goes alone which was a big mistake.  If he's not real careful, he could die before he solves this case...
