"That may be," criticized the officer, "but I don't see that it leads anywhere."
"One minute," returned Jack, "his hand was dusty because he came in through a dusty way."
"Plato, thou reasoneth well," laughed the judge, "but we are still up against the original puzzle. What was that way?"
"How long since these windows have been opened?" asked Jack, going to one of the windows that looked on the wall of the next building.
"Not in years, I think," answered the judge. "Why?"
Without replying Jack opened one of the windows and looked out; then going to a second he did the same.
"You don't think that they came in that way, do you?" questioned the officer.
"What do you expect to find, Jack?" asked Rand.
"There you are!" he cried triumphantly, when he came to the third window; "there is where they got in!"
"How do you make that out?" demanded the judge.
