In the quaint town of Meadowgrove, a body lay cold. The victim, Mr. Archibald Green, was found in his study. His eyes stared blankly at the ceiling. A single gunshot wound marred his chest. Beside him, a revolver rested on the floor. The room was undisturbed, save for one detail. A window stood open, a light breeze whispering through the curtains. Detective Amelia Hart arrived, her boots echoing on the wooden floor. She surveyed the scene, her keen eyes missing nothing. The clock ticked, each second echoing the start of her investigation.
