Model response

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.
