The midnight rain hammered the ancient windows of Ravenshollow Manor, echoing like mournful drums in the empty hall of night. Detective Marlowe stepped inside, his trench coat dripping with shadows, eyes scanning the blood‑stained marble floor for invisible whispers today. A pale figure lay sprawled across the oak table, a silver candelabra knocked over, its wax pooling like frozen tears. Marlowe's mind raced, calculating motive, noting shattered vase, ajar door, lingering perfume, and a single bloody fingerprint on the rug. The storm outside intensified, rattling the shutters, while the grandfather clock chimed ominously, marking the hour of the silent murder.
