Darkness enveloped the silent mansion. Detective Lily Jameson approached cautiously. Her flashlight illuminated the grand entrance. Bloodstains marred the expensive marble floor. A body lay in a pool of crimson. The victim's eyes stared blankly upwards. Lily knelt beside the lifeless form. She examined the fatal gunshot wound. Bullet casing glinted nearby on the floor. Lily donned gloves and picked it up. She sniffed the casing, smelling gunpowder. Footprints led towards the study door. Lily followed them, heart pounding in her chest. The study was in total disarray. Papers were strewn across the floor. Furniture lay overturned and broken. Lily noticed a threatening letter on the desk. She read it aloud, "Payback's a bitch."
