He had been caught "with the goods on him." All that loot hidden under the old barn on his place was positive proof of his guilt.

Still he held out, and declared himself the victim of some base plot calculated to ruin his reputation; which was rather a queer thing for Leon to say, since the only reputation he had in Scranton was for badness.
Another thing was that he still declined to betray his pal, for everyone felt positive he had had company when foraging through the cases in Paul Kramer's establishment, taking such things as naturally appeal to a boy's heart--candy, cigarettes, revolvers and sporting goods.
