The storm rattled every window in the abandoned manor as Detective Harlow found a lifeless guest near the dark hearth. No one admitted hearing the fatal argument, yet fresh wet footprints crossed the muddy hallway toward the locked library door. A silver letter opener lay beneath the victim's empty chair, its polished handle wiped clean except for one careless thumbprint. Harlow pocketed the small clue and turned toward the gathered suspects, knowing one polished smile concealed a calculated killer tonight.
