Cold rain lashed violently against the tall windows of Blackwood Manor, obscuring the dark silhouette standing near the garden gate. Inside the dimly lit study, Lord Harrington lay completely motionless beside his mahogany desk, a silver dagger in his chest. Crimson blood pooled slowly across the expensive Persian rug, staining the intricate floral pattern in a horrifyingly symmetrical dark circle. Inspector Thorne carefully picked up the shattered gold pocket watch from the floor, noticing its hands stopped precisely at midnight. Suddenly, the heavy wooden door behind him swung shut with a deafening crash, locking everyone inside the cold, shadowy room.
