Detective Harper stepped into the dimly lit study cautiously. Her sharp gaze scanned the room for hidden clues. The air smelled faintly of cigars and something metallic. On the desk lay an open envelope with no return address. A single drop of blood stained the edge of the paper. Beside it rested a pen, its tip smeared with ink. The grandfather clock in the corner ticked loudly, filling the silence. A half-empty glass of whiskey sat abandoned on the windowsill. Outside, rain tapped against the window, distorting the view of the garden. Harper knelt to examine a faint scuff mark on the wooden floor.
