The rain pattered against the window, casting an eerie glow on the dimly lit study. Detective Grayson stepped into the room, his eyes scanning the scene. A pool of blood stained the ornate Persian rug, the victim's lifeless body sprawled in the center. Grayson knelt beside the body, searching for clues. The victim's wallet lay open on the desk, its contents undisturbed. Grayson carefully examined the area, looking for any sign of a struggle. Footprints in the dust led towards the fireplace, the embers still glowing faintly. Grayson followed the trail, his mind racing with possible explanations.
