Heavy rain beat relentlessly against the tall library windows while Detective Arthur Pendelton examined the lifeless body on the floor. Lord Blackwood lay sprawled across the expensive Persian rug with a silver letter opener buried deep inside his silent chest. A shattered crystal glass rested near his cold right hand, spilling dark red wine onto the polished oak floorboards below. The heavy wooden doors had been locked from the inside, leaving the baffled police officers with no obvious escape route. Somebody inside this isolated country manor had committed a cold murder before the midnight clock finished striking twelve loud times. Arthur noticed a wet footprint near the velvet curtains, proving the clever killer was still hiding somewhere within the house. He pulled a small leather notebook from his wet trench coat and prepared to question the nervous family members upstairs.
