Enhanced descriptions from Syndetics:

"Axelrod crafts an enjoyable, fast-paced read." --Publishers Weekly

Henry Kennis, Nantucket island's poetry-writing police chief who will remind readers of Robert B. Parker's Jesse Stone and Spenser, works a second challenging case in Nantucket Five-spot.

At the height of the summer tourist season, a threat to bomb the annual Boston Pops Concert could destroy the island's economy, along with its cachet as a safe, if mostly summertime, haven for America's ruling class. The threat of terrorism brings The Department of Homeland Security to the island, along with prospects for a rekindled love affair--Henry's lost love works for the DHS now.

The "terrorism" aspects of the attack prove to be a red herring. The truth lies much closer to home. At first suspicion falls on local carpenter Billy Delavane, but Henry investigates the case and proves that Billy is being framed. Then it turns out that Henry's new suspect is also being framed--for the bizarre and almost undetectable crime of framing someone else. Every piece of evidence works three ways in the investigation of a crime rooted in betrayed friendship, infidelity, and the quiet poisonous feuds of small town life. Henry traces the origin of the attacks back almost twenty years and uncovers an obsessive revenge conspiracy that he must unravel--now alone, discredited and on the run--before further disaster strikes.
