From the Publisher:
Private detective Joe Quinn gambles. That's how he's lost his job, car, clothes, and girlfriend; it's why he's hitchhiking from Reno to California. At The Tower, a back-country compound housing a religious cult, Quinn gambles again, when Sister Blessing asks him to locate one Patrick O'Gorman. It proves to be no easy task: O'Gorman's dead - and, Quinn wagers, not so accidentally as everyone insists.
