The rain fell steadily, drumming on the roof of the old Victorian house. Detective Sarah Hayes arrived at the scene, her coat drenched and her mind racing. The body lay sprawled on the floor, a crimson pool surrounding the victim's head. A single bullet hole marked the wall, evidence of the fatal shot. Sarah knelt down, examining the scene with a practiced eye. The room was silent, save for the sound of her own breathing. She noticed a broken vase near the body, its shards glinting in the dim light. A sense of unease crept over her, as if something was amiss. The victim's face was frozen in a look of surprise, eyes wide and mouth agape. Sarah stood up, her mind already piecing together the clues. She knew this case would be far from simple, and the truth was waiting to be uncovered.
