The Launch Boys' Adventures in Northern Waters Part 3

"The first proof I get that he is playing double," muttered Alvin, "I'll order him off the boat and never let him set foot on it again, and, if he belongs to that gang of post office robbers, I'll do everything I can to have him punished."

One of the most discomforting frames of mind into which any person can fall is to see things which make him distrust the loyalty of one upon whom he has depended. It might be Alvin Landon was mistaken and Stockham Calvert was in reality a Pinkerton detective whose sole aim was to bring these criminals to justice; but, as I have shown, the full truth was still to be learned.

And Chester Haynes' feelings were the same as those of his chum. He glanced at the man who was puffing his perfecto, and wondered who he really was and what was to be the end of this curious adventure upon which he and Alvin had entered.

It was a brief run out to the Sheepscot, and the _Deerfoot_ headed up the river again toward Wisca.s.set. A steam launch was seen off to the left and a catboat skimmed in the same direction with our friends. Both were well over toward Westport, the left-hand bank, and slight attention was given them.

The _Deerfoot_ had not reached the upper end of Barter Island when Alvin from his place as steerer called out:

"That looks like the boat we are hunting for."

Running closer in to the right sh.o.r.e than the _Deerfoot_, a second boat was visible whose similarity of appearance caused astonishment. The bows of the two being pointed toward each other, the view was incomplete at first, but since the speed of each was all of ten miles an hour, they rapidly came opposite. Alvin sheered to the left, so as to make an interval of a hundred yards between them. Chester had caught up the binoculars and kept watch upon the launch, his companions doing what they could without the aid of any instrument.

"It's the _Water Witch_!" said Chester excitedly.

A minute before he did so, Detective Calvert quietly slipped from his seat to the floor, removed his hat and cautiously peered over the taffrail. But he did not cease smoking his huge cigar, and it struck Alvin when he looked around that his head was high enough to be in plain sight of anyone watching from the other craft.

Mike Murphy caught the stir of the moment.

"How many pa.s.sengers do ye obsarve on the same frigate? It seems to me there be only two."

"That is all that are visible," replied Chester, holding the gla.s.s still leveled.

"Thin they must be them two that we had the shindy wid the ither night!"

"Undoubtedly; in fact I recognize the one you pointed out at Boothbay."

"And the ither must be the ither one."

"There is every reason to believe so."

"Thin----I say, Captain," said the agitated Mike, turning to Alvin, "would ye be kind enough to run up alongside that ship?"

"Why do you wish me to do that?"

"I wish--that is--I wud like to shake hands wid that gintleman and ask him how his folks was whin he last heerd from them. Just a wee bit of friendly converse betwaan two gintlemen--that's all. Come now, Cap, be obliging," continued Mike, in a wheedling tone which did not deceive his superior officer.

"I faal a sort of liking for the young gintleman and should be much pleased if ye would give me a chance to have a few frindly words wid him--I say, Cap, ye're losing vallyble time, fur we're pa.s.sing each ither fast."

"No, Mike--not to-day; I have no objection to your having a little 'conversation' with Mr. Noxon or his companion, but this isn't the right way to go about it."

"I hope ye didn't suspict that I had any intintion of saying harsh wurruds to them, Cap!" protested the Irish youth, in grieved tones.

"Not words particularly, but there would be enough rough acts to make things lively. Chester, let me have the gla.s.ses, while you take the wheel for a few minutes."

They hastily exchanged places, and steadying his position, Alvin pointed the instrument at the receding launch. Detective Calvert still knelt on the floor and peeped over the side of the boat. He did not ask for the binoculars nor did the owner offer them to him.

Suddenly Alvin slipped down beside his friend in front and pa.s.sed him the instrument, as he resumed the wheel. While doing so, he whispered in a voice so low that no one else could hear what he said:

"Look just behind the fellow who is steering. He's Noxon, I'm sure! Study closely and let me know whether you see anything suspicious."

Wondering to what he referred, Chester complied. While doing his best to learn what his friend meant the latter whispered again:

"If you see anything, be careful to let no one besides me know what it is."

Chester nodded, with the gla.s.ses to his eyes. The opportunity for scrutiny was rapidly diminishing. Chester held the binoculars level but a minute when he lowered them again. The commonest courtesy compelled him to offer them to the detective.

"Maybe you can discover something," remarked the youth as he pa.s.sed them over. The posture of the man gave him the best chance he could ask, and he carefully studied the receding boat until it was so far off that it was useless to continue.

"Did you notice anything special?" asked Chester.

"I saw nothing but those two young men, with whom as I learn from the Captain he had an affray some nights ago."

Chester leaned over and whispered to Alvin:

"I saw it plainly."

"What?"

"A man crouching down among the seats as Calvert did and peering over like him."

CHAPTER IV

A STRANGE RACE

Suddenly the _Water Witch's_ whistle sent out a series of piping toots.

"What's the meaning of that?" asked Chester of Detective Calvert, who had quietly resumed his seat in one of the wicker chairs in front of the youth.

"It's a challenge to a race."

"I accept it," said Alvin, with a flash of his eyes. At the same moment he swung the wheel over and began circling out to the left, so as to turn in the shortest possible s.p.a.ce. "If that boat can outrun me I want to know it."

"Be keerful ye don't run over him," cautioned Mike, catching the excitement, "as Tam McMurray said whin he started to overtake a locomotive."

Alvin quickly hit up the pace of the launch, which sped down the Sheepscot with so sudden a burst of speed that all felt the impulse. The sharp bow cut the current like a knife, the water curving over in a beautiful arch on each side and foaming away from the churning screw.

Even with the wind-shield they caught the impact of the breeze, caused by their swiftness, and each was thrilled by the battle for mastery.

"Are you doing your best?" asked Calvert, watching the actions of the youthful Captain.

"No; I am making about two-thirds of the other's speed."

"Then don't do any better, is my advice," said the detective.

Alvin glanced over his shoulder.
