Thunder rattled the frosted glass windows of Blackwood Manor as midnight struck with a dreadful, hollow chime from far downstairs. Lord Harrington lay completely motionless beside his ornate mahogany desk, a heavy silver dagger lodged deeply inside his velvet waistcoat. Crimson blood seeped slowly across the antique Persian rug while the shattered remains of a vintage wine glass glittered nearby. Detective Vance knelt beside the cold corpse, carefully adjusting his spectacles before noticing the locked brass door from the inside. The ruthless killer had certainly escaped nowhere, which meant that someone among the seven terrified dinner guests was truly guilty.
