Rain drummed on the window. The old clock chimed midnight. A sudden scream shattered everything. Vance rushed down the stairs. The study door stood open. Cold wind blew the curtains. Lord Arthur lay very still. Red blood stained the carpet. A dagger pierced his chest. His dead eyes stared upward. He clutched a gold key. Only a black feather remained.
