The grandfather clock struck midnight precisely when Eleanor stopped breathing. Detective Marlowe arrived twenty minutes later, rain dripping silently everywhere. Her husband stood nearby, holding a bloody letter opener tremblingly. "I didn't kill her," he whispered, avoiding Marlowe's steady gaze. Marlowe noticed two teacups, but only one broken saucer remained. Outside, someone laughed, though the house was supposedly empty tonight.
