Dark clouds gathered above Blackwood Manor as Detective Hawke arrived. The grounds were silent, save for the distant sound of waves. Inside, the butler gestured toward the library where the body lay. Lord Pemberton's lifeless form was sprawled across the Persian rug. A single bloodstained dagger lay near his outstretched hand. Miss Eleanor Hartley, his niece, stood trembling near the window. Her eyes were wide with terror, though no one had entered. Detective Hawke knelt, noting the lack of footprints on the floor. A torn letter fluttered beneath the chandelier, its contents unreadable. The game was afoot, and secrets would soon unravel publicly.
