At age eight, Dave Austin witnesses the murder of his brother and a friend in the fields behind his house. Amnesia protects Dave from remembering what happened, and the killer escapes. Locals suspect an itinerant madman, a pedophile, or a disturbed friend, maybe driven mad by strange, psychedelic mushrooms with clown-like multi-colored caps. Ten years later college pressures and alcohol bring on the dreams. And each one dredges up a new, revealing memory. When the murderer strikes again, Dave senses the new crimes in visions. Seeing murders of teenagers as they happen where his brother died precipitates the crisis. He returns to his home town in central New York State, hoping to find his dead brother's friend, a man with his own psychological problems who may know what happened. Dave's appearance alarms his psychiatrist, the officers who hadn't solved the case, and especially the killer, who knows it was a mistake to let the young Dave escape. Memories do not stay repressed, and the killer vows to correct his mistake. A crazy farmer invites Dave to see the Clown Forest at midnight to solve the mystery and learn the killer's name, What Dave finds may identify the murderer. If it's the truth and he survives. This blend of mayhem and mental health makes for a mystery that stays unsolved until the end.
