The rain hammered hard against the windows of Blackwood Manor. Inspector Marlowe stepped inside, shaking cold water from his coat. The body lay in the study, discovered by the maid. Lord Ashworth had been dead for several hours at least. A single pistol bullet had ended his life around midnight. His eyes stared at nothing, frozen in one final surprise. Marlowe walked slowly through the room, noting every small detail. The window was locked from the inside, which puzzled him. No one could have entered or left through that window. Yet the killer had somehow vanished without leaving any trace. Marlowe knelt beside the body and studied the wound closely. Someone had fired the shot from very close range indeed. The victim knew his killer, Marlowe thought with grim certainty. Five guests were staying at the manor that fateful weekend. Each of them had a reason to want him dead. All of them carried secrets buried deep within their pasts. Marlowe lit his pipe and began his quiet, methodical investigation. The storm outside raged on, matching his dark mood perfectly. Somewhere in this house, a murderer waited with steady nerves.
