Rain lashed the tall windows. Thunder shook the isolated mansion. Lord Blackwood lay completely still. Crimson stained his silk vest. A bloody dagger rested nearby. The brass clock struck midnight. Loose boards creaked just outside. Someone watched from dark shadows. Detective Vance entered the library. He locked the heavy doors. Six nervous suspects stood waiting. One guest murdered their host.
