«Stone Cold» by Robert B.Parker

Jesse Stone has a problem no officer of the law likes to face: Dead bodies keep appearing, but clues do not. A man takes his dog out for a run on the beach, only to be discovered hours later — with two holes in his chest. A woman drives her Volvo to the store to do some grocery shopping, and is then found dead, her body crumpled behind her loaded shopping cart. A commuter takes a shortcut home from the train, and never makes it back to his house. Hunting down a serial killer is difficult and dangerous in any town, but in a town like Paradise, where the selectmen and the media add untold pressures, Jesse feels considerable heat. Already walking an emotional tightrope, he stumbles; he's spending too much time with the bottle, and with his ex-wife — neither of which helps him, or the case. And the harder these outside forces push against him, the more Jesse retreats into himself, convinced — despite all the odds — that it's up to him alone to stop the killing.
