Rain polished the manor windows while midnight swallowed distant thunder. Inspector Vale arrived precisely when the grandfather clock stopped ticking. Inside, twelve guests stood silently around Lord Ashcombe's empty chair. His dinner remained untouched, except for one crimson fingerprint nearby. No doors were unlocked, and every window was securely latched. Then someone noticed blood dripping slowly from the chandelier above. Vale looked upward and found Ashcombe staring lifelessly back down. Among the guests, a woman began laughing behind black lace. The inspector counted everyone twice, then quietly counted thirteen shadows.
