Detective Moore arrived at the mansion just past midnight. Rain lashed the windows while thunder rattled ancient bones. The body lay sprawled upon the library's Persian carpet. A broken wine glass dripped crimson onto white marble. The victim's eyes remained open, fixed on something unseen. Candles flickered as shadows danced along crumbling plaster walls. The study door remained firmly locked from inside, though. No fingerprints were found on any surface in the room. A sealed envelope rested upon the dead man's cold chest. Somewhere above, a grandfather clock began striking thirteen exactly.
