"What is the matter?" asked the train boy. "Has anything happened?"

"When did your room-mate leave?" asked the detective, not answering his question.

"I don't know; I only just woke up."

"Did you rest well?"

"That's a very queer question to ask me," thought Fred. "Yes," he answered, "I rested very well."

The detective and the clerk exchanged glances. This statement did not accord with what Fred's room-mate had said down-stairs.

"The bed was very comfortable," added Fred by way of compliment to the house.

"I am glad you found it so," said the detective dryly.

"Did you come upstairs to ask how I rested?' asked Fred, with a smile.
