Lord Harrington sat motionlessly in his plush leather armchair while dark crimson blood dripped slowly onto the expensive Persian rug. The ornate grandfather clock struck midnight with a heavy chime that echoed softly through the vast and silent manor library. A silver letter opener remained deeply embedded within his velvet jacket, piercing his cold heart with ruthless and deadly precision. Detective Miller quietly stepped into the dimly lit room, carefully ignoring the screaming maid who cowered near the open door. Nobody could leave the isolated island tonight because the violent storm had destroyed the last remaining bridge to the mainland.
