The others looked at each other as if they hardly knew what to make of it. Somehow this Langdon always did seem to have the advantage whenever they came face to face. In the canoe he was Pet’s master, because he felt quite at home there, while the other did not. Now, here ashore, he held something in his hands which none of them liked the looks of—a double-barreled shotgun.

“Aw, go chase yerself! ’Twan’t that as fetched yuh here. Think we scooped sumpin, an’ yuh come sneakin’ round tryin’ tuh see,” snarled the shivering Pet.

“Come up to the fire and keep warm. It’s your fire; I don’t lay any claim to it. Perhaps you fellows think I slid down that toboggan track on purpose? Well, you’ve got another guess coming, then. I have more respect for my clothes than to try such things, as a rule.”

Frank was talking for a purpose. He did not expect to enter the camp of the enemy when he parted from Will and Bluff; but now that circumstances beyond his control had caused such a move on his part, he meant to take full advantage of it.

Before he left, he expected to know positively what they had in that tent. If Jerry was found there, a prisoner, he must be set free, no matter what happened after such a move.

So, as he talked he kept moving a little at a time in the direction of the said tent. If the others noticed his action they could not give any sort of guess as to what he was after. Besides, he kept that gun always half raised, and moving back and forth, from side to side, so that it covered the entire bunch.

“Jest yuh make tracks outen here, Langdon. Yuh ain’t wanted, see? This here’s our camp, an’ yer intrudin’,” chattered Pet, who was compelled to creep closer to the fire, for he was shivering as though he had the ague.

“Oh! I’m going right away, boys. I assure you I haven’t the least intention of staying and putting you to any inconvenience. Just a little social call, you understand, Pet. I couldn’t bear the thought that possibly you were still floundering around out there on the lake. Glad to know you arrived,” Frank continued, now close to the flap of the tent.

The others had unconsciously followed him, so that with the exception of Pet the whole of the camp’s inmates were clustered just in front of the intruder.

As he uttered the last word, Frank suddenly stooped. He had seen his chance, and meant to investigate the interior of that tent.
