It was too late to call the landlord. Anderson went to the window and lit a cigarette. He looked out of the window. There was a tall house on the opposite side of the street. The lamp was behind him. He saw his shadow on the wall of the house opposite. The person in room 13 was also standing at the window. Anderson saw a second shadow on the wall of the house opposite. This second shadow was strange. The person in room 13 was wearing a tall, pointed hat. Also, the light from room 13 was red. The light was the colour of blood.
