The butler found Lady Ashworth dead beside the grand piano. A silver letter opener lay beneath her cold right hand. Rain hammered the tall windows of the dark silent house. Inspector Hale arrived before dawn with two silent young constables. No one claimed to have heard any cry that night. The locked library smelled of brandy, blood, and old paper. Her nephew swore he had been asleep upstairs all night. Yet fresh mud from the garden stained his evening shoes. A torn guest list lay inside the cold fireplace grate. Someone had burned one name before the police finally arrived. Hale studied every shadow and trusted nothing that he saw.
