A week went by. In the jail a sullen prisoner, always swearing his innocence, lay awaiting the outcome of Lester's injury, while day after day he lay tossing on his bed, delirious, or deep in a stupor from which it was difficult to rouse him.
The police were satisfied that they had the man who had struck down Lester, and had killed the dog, but doubts were creeping into Wugs' mind. He himself had interviewed the prisoner, not telling him who he was. The man would say nothing, but Wugs came off with the feeling that there was something queer afoot.
"It's the wrong man," his brain kept telling him over and over; and when he told the police that, and heard their shouts of laughter, the words kept repeating themselves over and over, "The wrong man!"
There was a Boy Scout meeting one night, and Wugs went. After the usual business was over, gathering them around him in a close group, Wugs went over the story of his brother's great invention, its try-out on the herd of cows, his home-coming, and the terrible ending to his triumphant day. Then in a still lower tone, as though he feared the very walls might turn traitor, he told them of his feeling that the man waiting trial for the attack on poor Lester was not the spy who had taken the formula.
"That's the thing to find out," said Wugs. "The Police are dead sure they have the right fellow, but I'll never believe it until I find that paper. You see, he didn't have a chance to mail it unless he had a confederate waiting outside to take it away. That's what we have got to find out."
"Why, 'course he had a what-you-call-it!" the Potter twins broke in.
"Slow down! Slow down!" begged Wugs. "Gee, how do you suppose anybody can tell what you say when you both talk at once? Let's have Porky; you claim to be the oldest."
"See how it was," said Porky, with a free field, leering at his disgusted brother. "'Me 'n' Beany'd been swimmin'. We went down to the old water hole where the springboard is, and some cloze was sitting the bank. We saw a man in the water, an' we watched him. Say, he could swim, he could! He could just live in the water. Well, we took off our cloze by-en-by, and went in, and pretty soon he come out. He never noticed us any more'n if we wasn't there; only he come out a good ways from us and walked back where was his things, without lookin' our way. But we seen him; his lip was twisted sort of funny, and made him look like a grin. We'll, he dressed like a streak, and stalked off; and Beany whispered, 'Where did you get that coat?' but seems we didn't like to yell it right at him. He had a funny look. So we swam and by-en-by we come away too."
"You forgot what we found," reminded Beany. "When we came where his cloze had been we found two papers. One was just a plain paper in a plain envelope, and the other was a card written all up, something about admit bearer to all parts of fairgrounds. I suppose he is going to show something at the fair next week. Anyhow he'll have to get another, because Porky lost it out the hole in his pants pocket goin' home. And the other paper-"
"Wait till you get to it, can't you?" said the other twin, glaring fiercely at himself, or so it seemed to the boys watching. "We ain't come to that. But we seen the coat all right. Well, we got on our wheels and started home."
"I had the paper in my pocket," interrupted Beany.
"Yes," said Porky simply. "Beany's pants was new. We come along through the village, and up just before you get to your first driveway, Wugs, my handle bars come loose, and we had to get off and fix 'em. And Beany looks up, and he says, 'Gosh! Here's another striped coat! And ain't it on a pirate!"
"I looked and, sure 'nuff, there come along another coat just like the one over to the swimmin' hole but if that feller was bad, this one was worse. He had a big black mustache and he looked at us like he'd like to eat us.
"When he went by," Beany says, 'Well, I bet he is a pirate all right!'
"So we went on home. And after supper when we come to your house, Wugs, why, you know about that, and there was another coat like the others being arre'sted. Then we went back; and mother wanted us to write it all to Uncle Jake. And the lamp made Beany's head hot, and he took the funny thin paper we found over to the swimmin' hole and made a sort of shade of it. And when we had our letter done, Beany went to take down the shade and, honest to gosh, boys, it was all written on! Wouldn't that frost you? I s'pose you think we're lyin'; but it's true. All writin' on two sides!"
"What did you do with it then?" demanded Wugs.
"We showed it to mom and she took it and put it in her pocket."
Wugs groaned.
"You see, Wugs, they's three of those coats and every one's worse than the other," finished Porky.
"We must find those men. Who is going over to patrol the fairgrounds this year beside me?" said Wugs.
"Me and Porky," said Beany proudly.
"What's the first thing to do?" asked Porky.
"Well, one of you fellows who are not detailed to the fair had better go over to the Troop D Farm where the Mounted Police are training, and see when I can see Colonel Handler."
"What you want of him?" asked a boy named Asa Downe.
"I want to tell him enough of this so he will fix it to let us
Scouts go wherever we like. So the first thing in the morning,
Asa, you trot over there, and find out when I can see the
Colonel."
Asa started for the Troop D Farm as soon as he had finished a hasty breakfast the next morning. He had his part of the interview with Colonel Handler nicely and neatly rehearsed. He had worked so hard over it that he said, "Thank you, Colonel," when his mother had passed the doughnuts at breakfast.
The more Asa thought of it, the more he thought it would be fine to take some one along with him; and when he saw ahead of him the two violently red wheels of the Potter twins, it was settled right there. He yelled, and they waited.
"Where you goin'!" he demanded.
"Over to the Troop D Farm," said Porky, hopping off his wheel to rest.
"What for? This is my job."
"Sure it is!" agreed Beany. "But we knew you'd want some one along for fear you forgot of the things you wanted to say, and we knew we always remember better than the other fellows. So we started out. We knew you'd be along."
"All right, you're on!" said Asa and they pedaled rapidly along the beautiful country road. When they reached the Farm, they found that the Colonel, who stayed at Syracuse with his family, had not yet arrived. The men were grooming the beautiful horses, rubbing up the bridles, and airing saddle blankets.
Porky and Beany and Asa, sitting on the stone wall at the side of the barn, watched and admired.
"That's what I'm goin' to be"' whispered Porky.
"Sure!" agreed Beany. "Wonder how long it will take us to get that high?"
"Dunno," said Porky. "I outgrew two pairs of pants last year!"
"Here's the Colonel," said Asa as a big car was driven up and an officer stepped down.
"Wait! Wait!" said Asa, swallowing rapidly. "Let him get through talking first. You see, he has charge of all the country patrols, and 'course he wants to give them orders. Gee, how the spies must hate him!"
As though in answer, a long, low racing car rolled smoothly and silently up, and stopped in the road just opposite where the boys sat on the stone wall. On the little rise where stood the low, rambling farmhouse, the Colonel, with only a glance at the strangers, turned his back as though refusing to be interrupted, and went on with his orders.
In the car, one of the men half rose, leveled a revolver full at the Colonel's broad back, and fired. But almost before he could take his flashing aim, an unearthly screech volleyed from the Potter twins, and from Beany's good left hand a cobble whizzed through the air, and struck the assassin's shoulder. It destroyed his aim. The bullet went wild, and before he could recover, the Colonel had whirled. With a muttered curse the would-be intruder fired full at the boys, dropped to the bottom of the machine, and the car shot forward will in incredible speed.
Leaping from the veranda with the agility of a boy, the Colonel barked out a volley of sharp orders. Men came swarming from their quarters. A man hurried to the telephone. Horsemen dashed madly up the road. A slim, capable-looking racer slid from the garage, and the Colonel and a couple of aides came down where the boys still stood grouped beside the stone wall. Beany held a flattened bullet in his hand. It had struck beside him.
