The cold autumn wind swept through the shattered windows of the abandoned Victorian mansion while the weary detective stepped inside. Blood stained the ornate carpet near the fireplace where the victim lay perfectly still beneath a broken crystal chandelier fragment. A silver pocket watch rested beside his outstretched hand with the cover popped open to reveal a hidden secret compartment. He knelt down and listened carefully for any lingering whispers that might guide him toward the identity of the killer. Shadows stretched across the dusty floorboards as a distant clock began to chime the midnight hour with a mournful tone.
