The rain drummed against the library windows as Detective Morrison arrived, her trench coat soaked from the evening storm. Inside, the body of Professor Whitmore lay sprawled beside the shattered remains of his antique desk lamp. The butler, trembling slightly, explained that he'd discovered the scene moments after hearing a loud crash from the study. Morrison knelt beside the victim, noting the single bullet wound to the chest and the missing pocket watch that had been his most prized possession.
