"No, one light is burning."

"Wait!"

The door opened again, and two men in evening dress came out on to the steps.

"There are two men," said the boy, "but only one wears a hat."

"Describe him to me."

"He is not tall, he is thin, but I cannot see his face for his hat."

"Look! look well!"

"He goes back into the house. He takes off his hat. Wait! He is smoking. He strikes a match and holds it to his mouth. I can see him now."

"Well! Of what colour is his hair?"

"Very fair--yellow. His face is round, his eyes are light."
