Thunder rattled the windows of the abandoned mansion at midnight. Detective Marlowe's flashlight revealed blood stains upon the wooden floor. A gunshot echoed through the corridors, chilling Detective Marlowe's nerves. Moonlight cast long shadows across the grand staircase's half-fallen steps. Somewhere upstairs, faint footsteps betrayed the killer's hurried escape route. A silver locket lay broken near the body's unfamiliar silhouette. Marlowe's heart pounded as he realized time was running out.
