The moon cast long and jagged shadows across the mahogany floorboards while the grandfather clock chimed exactly twelve lonely times. Lord Harrington slumped silently within his leather armchair with a delicate crystal glass still clutched tightly in his cold hand. A single drop of crimson blood stained his silk cravat like a sinister rose blooming against the stark white fabric. Detective Miller stepped over the threshold and immediately noticed that the heavy oak door had not been locked from inside. Broken glass lay scattered beneath the open window although the silver latch appeared to be completely untouched by any intruder. Bitter almond scents lingered in the stagnant air while the distant barking of a hound echoed through the desolate moor.
