To say they were surprised would not have half expressed it. They were dumbfounded and mad—clear through. So here were these rascals, turning up as they always did, just in time to spoil the fun.

That Buck and his cronies had been talking about them was evident from the fact that at the appearance of the radio boys they stopped short in what they were saying and looked sullenly abashed. And from their confusion Bob guessed that the meeting was as much a surprise to the “gang” as it was to themselves.

The boys would have gone on without speaking, hoping to avoid trouble if it was possible, but Buck hailed them boisterously.

“Say, what are you guys doing here?” he asked, sneeringly, thrusting himself almost directly in front of Bob, so that the latter would be forced to step aside in order to pass him.

“That’s what I’d like to ask you,” returned Bob, feeling himself grow hot all over. “Get out of my way, Buck. You’re cramping the scenery.”

“Aw, what’s your awful rush?” asked Buck, refusing to move, while Carl Lutz and Terry Mooney sidled over to the bully, keeping a wary eye on Bob’s right fist, nevertheless.

“Say, get out of here, Buck Looker, and get quick!” It was Joe who spoke this time, and any one not as stupid as Buck Looker would have known it was time to do as he was told.

But because of the fire that had burned to the ground his father’s disreputable cottage in the woods and which he and his followers had blamed upon the radio boys, Buck Looker thought himself safe in taunting the latter as much as he wished. He assumed that they would not dare resent anything he said or did, for fear he would make public the matter of the fire and accuse them openly.

It was a chance of a lifetime for Buck—or so he thought—and he was determined not to over-look it. So his manner became more insulting than ever and his face took on a wider grin as his glance shifted from Bob to Joe.

“So you’re in a hurry, too, are you?” he sneered. “Going to set some more houses on fire, eh?”
