It's August in New York -the dog days- and Michael Carpo needs a getaway. Relief comes when his old friend, Jack Crawford, offers his home overlooking Lake Lillinonah in sleepy Bridgewater, Connecticut. But Carpo's plans for a restful vacation end the day he arrives, when he discovers Crawford's lifeless body sprawled in a pool of blood. Local authorities rule it suicide, and even Carpo can't explain away his friend's hideously slashed writsts. But for Carpo, suspecting the worst comes with his job-and he's beginning to suspect murder.
