"You are sharp, my young friend," said the detective, "and I think I may say wonderfully cool under the circumstances."

"Under what circumstances?" asked Fred, his attention drawn to the last part of the detective's speech.

"There was a burglary committed yesterday afternoon in Elmira," said the detective, fastening his eyes keenly on the face of the train boy.

"Was there?" asked Fred, not seeing in what way this information was likely to affect him. "I thought most burglaries were committed in the night."

"They are, generally, but this was an exception. There was no one in the house except old Mr. Carver, who is quite hard of hearing. The burglary probably took place about five o'clock, and the burglar is supposed to have taken the 5:51 train from Elmira."

"Why, that is the train I was on," said Fred in surprise.

"By a curious coincidence," said the detective with a queer smile, "it was by your train that the burglar probably traveled."

His tone was so significant that Fred asked quickly, "What do you mean?"

"I mean, my young friend," said the detective, "that you are suspected to know something of this affair."

"If you are a detective," retorted Fred, "I don think much of your sharpness. I have never been in Elmira in my life."
