Turning around, there stood a petite girl with a short black bob, gazing into the room with sharp eyes. In her arms, she held a large sketchbook and a black marker.
"............"
Without uttering a single word, the girl pulled the marker cap off with her teeth and, with fluid strokes, began writing across the sketchbook's page.
"The air conditioner's outdoor unit. The inside of the drain hose is rigged. The locked-room trick was set up after entering. The weapon is at the bottom of the elevator shaft."
