The caretaker was very much surprised and not a little annoyed at the effect his answer had upon the four boys.

"I don't see anything humorous about that!" he said as the lads threw themselves down on the bunks and roared with laughter.

"It looks funny to me!" Tommy replied. "It we had never showed up here, the mine wouldn't have been flooded. As soon as we start away or promise to leave the district, which amounts to the same thing, this cheap skate of a detective finds the break, and all is well again!"

"Why, you don't think that he had anything to do with the trouble at the mine, do you?" questioned the caretaker.

"Oh, of course not!" replied Sandy. "Ventner had nothing to do with cutting the ladder. That fellow will land in state's prison if he keeps on trying to murder boys by sawing ladder rungs!"

"I had forgotten that,' said Canfield.

"Well, don't forget that this man Ventner is playing the chief villain's role in this drama!" Tommy advised. "And another thing you mustn't forget," the boy continued, "is that you're not to say a word to him that will inform him that he is suspected."

"I think I can remember that!" replied the caretaker.

The boys prepared a hasty supper and then, suit cases in hand, started for the little railway station. There they inquired about the arrival and departure of trains, bought tickets, and made themselves as conspicuous as possible about the depot.

"Keep your eye out for the third boy," George chuckled, as the lads walked up and down the platform.
