Rain tapped against the station. Inspector Vale found the body. The victim’s watch ticked backward. Someone had locked every window. Yet footprints crossed the ceiling. Vale heard faint laughter upstairs. Nobody else had heard it. Then the telephone rang twice. Dead men never called first. Vale answered, breath held tight. Someone whispered, “You’re late, Vale.”
