The lighthouse keeper found the body before cold dawn arrived. Rain washed the pier while gulls circled silently above them. Victor Hale lay motionless, his throat cut with surgical precision. No footprints disturbed the dust inside his locked office door. But someone had stolen the brass key from his pocket. Detective Mara Quinn arrived alone, sensing the island would resist. She knelt beside him and whispered, who knew your secrets?
