The man was of medium size, with dark hair and dark eyes, and as he wore a dark grey overcoat and a slouch hat, the cadets immediately put him down for the individual mentioned to them by the storekeeper. He had a quiet smile on his face which was reassuring to all of the lads.
"What is it you want to know?" questioned Fred.
"Are you the Rovers from Colby Hall—the young men who had so much to do with rounding up those Germans at Camp Barlight and capturing that hidden submarine?"
"Yes."
"And you also helped in rounding up those other fellows who were trying to put through some deal with two men named Brown and Martell?"
"We did," said Andy.
"It was a fine thing to do, and it shows that you fellows are true blue," returned the man, with satisfaction.
"Are you a Secret Service man?" questioned Jack suddenly.
"Why do you want to know that, Rover?" was the counter question.
"If you belong to the Secret Service you are just the man we are looking for."
