Henry Kennis, Nantucket island's poetry-writing police chief works a second challenging case. 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 summer-time, 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.
