Detective Marlowe arrived at the old Victorian mansion just as the cold rain began falling across the sleepy coastal town. The victim's body lay sprawled across the Persian rug in the library, a silver letter opener protruding from her chest. Her name was Eleanor Whitmore, the famous novelist whose explosive latest book had threatened to expose secrets nobody wanted revealed. Six guests had gathered for the weekend party, and every one of them had a reason for wanting Eleanor dead. Marlowe noticed the smashed window first, then the muddy footprints leading toward the dark garden, then the empty manuscript drawer. Something about the scene felt deeply wrong to him, though he could not yet say precisely what it actually was. The grandfather clock in the hallway had stopped at eleven, marking the precise moment when Eleanor's life had finally ended. Outside, thunder rumbled ominously over the churning sea, and the phone lines had been cut sometime during the stormy night. They were all trapped here together now, waiting for a killer who was certainly still standing among their frightened faces. Marlowe lit his last cigarette, studied each suspect carefully, and began asking the questions that would ultimately shatter their lives.
