The rain soaked the cobblestones outside the grand old manor. Inside, the clock struck midnight with a low solemn chime. Lady Whitmore lay dead upon the library's crimson Persian rug. A silver letter opener rested near her pale outstretched hand. The inspector observed the room with eyes cold and sharp. A broken wine glass glittered beneath the mahogany side table. Her husband claimed he had been sleeping upstairs all night. But the butler's eyes flickered toward the locked garden door.
