Rain hammered the windows of Blackwood Manor that bitter night. Inside, twelve guests waited in the hall for their host. Lord Blackwood had not appeared; silence sharpened every nervous whisper. A grandfather clock ticked loudly beside the cold marble fireplace. Suddenly, the heavy oak doors swung open without a sound. No servant entered, yet a single red glove lay inside. Detective Mara Vale stepped forward and studied the glove carefully. Something dark stained its fingers, and the room fell silent. Then a shrill scream echoed from the locked study upstairs. Mara rushed upstairs and found Blackwood dead at his desk. A bright silver letter opener stood upright in his chest. The locked window and red glove promised a patient killer.
