The rain drummed against the steady glass while the clock chimed midnight within the lonely and silent country manor house. Arthur stood over the body and noticed that the silver letter opener was still buried deep inside the dead man. No one had heard the muffled scream because the violent storm outside drowned every single sound within the thick walls. Crimson blood stained the expensive Persian rug where the master of the estate had collapsed after his final desperate struggle. The heavy smell of expensive brandy and iron filled the air while the detective pulled his notebook from his pocket. Someone in this locked room was a cold killer and the shadow of suspicion now fell upon every single guest.
