Rain hammered the manor windows as Detective Mara Cole stepped over the body lying in the study's dark crimson pool. The victim, a famous banker, stared upward with glassy eyes, his silver letter opener buried deep within his black waistcoat. A clock ticked loudly above the fireplace while one frightened servant whispered that no stranger had entered the locked house. Mara knelt down, noticed a torn theatre ticket, and soon knew the killer had planned this elegant murder before midnight.
