Rain hammered relentlessly against the tall, stained glass windows of Blackwood Manor as midnight struck with a heavy chime. Detective Julian Vance dusted off his damp tweed coat, stepping carefully over the threshold into the dimly lit foyer. A grand chandelier swung overhead, casting eerie shadows that danced across the faces of the gathered, visibly trembling houseguests. Lord Harrington lay slumped in his leather armchair beside the roaring fireplace, a silver dagger protruding from his chest. Nobody had dared to touch the body, nor had anyone left the opulent drawing room since the horrifying discovery. Julian knelt down near the victim, pulling a small magnifying glass and a leather notepad from his deep pocket. The victim's eyes were still wide with terror, reflecting the dying embers of the fire in the quiet hearth. A faint scent of bitter almonds lingered softly in the cold air, masking the metallic smell of fresh blood. Everyone present had a clear motive for wanting the wealthy old patriarch dead before the morning light finally broke. Julian looked up slowly at the five nervous suspects, knowing one of them was a cold, calculating killer. "Do not move an inch," the stern detective commanded, "because the culprit is certainly standing inside this very room."
