Autumn has come to Bucks County, and Steve Levitan has a new job: develop a conference center for Eastern College at Friar Lake, a few miles from campus. But on his first visit to the property, his golden retriever Rochester makes a disturbing discovery, a human hand rising from the dirt at the lake's shore.

Whose hand is it? Why was the body buried there? The answers will take Steve, his photographer girlfriend Lili, and the ever-faithful Rochester to a drop-in center for recovering drug addicts on the Lower East Side, a decaying church in Philadelphia's Germantown, and finally to a confrontation with a desperate killer.
