Thunder rattled the frosted leaded windows of Blackwood Manor as midnight struck with heavy, ominous chimes from the grandfather clock. Detective Miller pushed open the heavy oak library doors, shivering as an icy draft extinguished his flickering wax candle instantly. Lord Harrington lay sprawled across the ornate Persian rug, a silver letter opener protruding viciously from his embroidered silk waistcoat. Beside the dead nobleman's limp hand, a shattered porcelain teacup leaked dark Earl Grey across a fresh sheet of parchment. Scrawled in smeared crimson ink upon that paper was a single desperate word that implicated everyone inside the locked mansion.
