The rain fell heavily outside. Blood stained the marble floor. Detective Miller knelt beside it. A silver knife lay nearby. The victim wore red silk. No one heard the scream. Shadows danced on the wall. The clock struck twelve times. Miller touched the cold hand. The door remained slightly open. Footsteps echoed in the hallway. Someone watched from outside now. The mystery starts here tonight.
