The detective walked into the dark room slowly and carefully. Rain fell heavily outside the window while he searched alone. A woman lay dead upon the bloodstained Persian wool rug. Inspector Blackwood examined the knife with his gloved left hand. Shadows danced across the walls as thunder shook the house. Someone had clearly wanted her death to seem like suicide. The clock on the mantelpiece stopped at exactly three o'clock. Blood pooled around her head forming a dark crimson lake. He noticed the window was locked from the inside always. A red rose lay crushed beneath her cold pale fingers.
