A cold rain lashed the gothic mansion's windows as Inspector Graves entered the silent foyer alone with a drawn revolver. The body lay crumpled near the grand staircase, a crimson pool spreading beneath the marble like an abstract dark painting. Graves noticed a single black glove lying on the step above the corpse, its fingers curled upward desperately toward him. He did not touch it, for the scene demanded careful observation before any conclusion could be drawn from the evidence. A faint ticking echoed from the study, but the grandfather clock had stopped hours ago yet its sound persisted oddly. Graves frowned, realizing the murder weapon was missing, so he glanced toward the door where a shadow flickered past him.
