Detective Miller stared coldly at the bloody corpse on floor. Heavy rain battered the dark window panes of old mansion. Someone had locked the heavy oak door from the inside. A silver dagger protruded deeply from the victim's pale chest. No footprints disturbed the thick dust covering the antique rug. Everyone in the wealthy family possessed a dark hidden secret. Time was running out before the killer struck once again.
