A CASE FOR THE AUTHORITIES.

It was just after breakfast the next morning that a big automobile skimmed past the Prescott home. Peggy and Roy saw it from the windows.

"Why, that's Sheriff Lawley," exclaimed Peggy. "And look, old Mr. Harding is with him, and that Mortlake man."

"That's right. Wonder where they can be going?" said Roy, sauntering out to the garage at the back of the house and giving the matter little more thought. It had been arranged that he was to bring the aeroplane back that morning, driving over with Peggy, Jimsy and Jess in the car, and skimming home in the Butterfly while a part of the party brought the car back. They were to call for Jess and Jimsy at their home, a fine residence overlooking the Sound from a lofty hill.

Jess and Jimsy were waiting for them, and, almost before the car had stopped, they were at its side.

"Heard the news?" asked Jimsy breathlessly.

"No. What is it?" demanded Peggy eagerly.

"Why, that safe at the farm-house was robbed last night. All the money was taken, and they have no clue to the thief."

"How did you hear of it?" asked Roy incredulously. Peggy had told him of the queer wall safe.

"The 'central' told one of the servants and she told Jess. Strange, isn't it?"

"It is odd," agreed Roy. "But if people will keep their money in such places, it is hardly surprising if they lose it. Did you hear any details?"

"No, but no doubt we shall when we reach the farm-house," put in Jess; "isn't it thrilling, though?"

"Not very thrilling for poor Galloway, who lost the money," said Peggy. "I expect he didn't make it any too easily."

On their arrival at the Galloway farm-house, the young people found a scene of great excitement. The sheriff, red-faced and important, was examining several farm hands beneath one of the big elms, while in the background stood the farmer and his wife, looking somewhat perplexed, as well as worried.

As the Prescott auto drove up, old Mr. Harding, in his usual rusty black suit, rose from his seat under the elm, and whispered something to the sheriff. The blue-chinned, thick-necked Mortlake arose also. All three turned and gazed curiously at the young occupants of the car, as it slowed down.

"Good morning, Mr. and Mrs. Galloway," cried Peggy. "We were dreadfully sorry to hear of your loss. Have you any clue yet?"

There was something curiously cold in the woman's voice, as she replied in the negative. Her husband looked sullen and merely nodded. The sheriff now rose and came toward the machine. He knew all the young folks and greeted them briefly. At his heels pressed old Harding and his companion. They whispered in the sheriff's ear as he advanced, and seemed to be urging him to something.

"I understand that you folks was in this house yesterday afternoon?" began the sheriff abruptly.

"Why, yes, during the storm," said Peggy. "There was Lieut. Bradbury, of the United States Navy——"

Harding and Mortlake exchanged annoyed glances. This was confirmation of their fears.

"Yes, go on," urged the sheriff.

"And myself, and Mr. Bancroft here and his sister, and later my brother came."

"Do you recall the safe being opened while you were in the room? I presume from the remark you made when you drove up that you know of the robbery."

"We heard of it at the Bancroft's, but we don't know the details."

"That is not necessary. Answer my questions, please. Who was in the parlor beside yourself when Mr. Galloway opened the wall safe to reward the men who had helped him extinguish the fire?"

"Why, Jimsy—I mean Mr. Bancroft—his sister and Lieut. Bradbury, beside, of course, Mr. and Mrs. Galloway."

"What! Your brother was not there?"

"Certainly not. He didn't come till later."

"Then your brother didn't see the safe opened?"

"Of course not," struck in Roy. "I was here only a very brief time. But what does all this mean? I don't understand."

"It means that you are cleared of a grave suspicion," said the sheriff. "Mr. Harding and Mrs. Galloway's brother, Mr. Mortlake, here——"

"Her brother!" exclaimed Peggy in an undertone.

The sheriff went on:

"Seemed to have an idea that Roy Prescott was here at the time. They even went so far as to intimate that——"

But old Mr. Harding was tugging frantically at the sheriff's arm. He was seconded by Mortlake. Interpreting the signals aright, he stopped short.

"In fact, it looked suspicious," he concluded lamely. He turned and went off, followed by Harding and Mortlake.

"How did you ever come to make such a mistake?" snarled old Harding, as they walked away much crestfallen, "we haven't a leg to stand on, now."

"Why, confound it all," retorted Mortlake, "my sister mentioned a young man being with the girl in the aeroplane, and I took it for granted that it was her brother."

"And a nice mess you've got us both into, with your 'taking it for granted,'" snorted the old miserly financier of Sandy Beach. "It looks as if we'd got ourselves in a trap now."

"Nonsense. Who's to know we have the money? I'll take the first opportunity to send it back, and no more will be heard of the matter. Lucky I didn't hide it in his aeroplane, as I intended to do."

"Yes; but we've still got the cub as our rival. I wish I could think of some plan to choke him off. That scheme of yours to blame the robbery on him would have been all right if you'd only made sure of your facts first."

"Don't worry. Our chance will come yet. I'll make that whole outfit regret bitterly that they ever stole a march on us by kidnapping that officer."

"To have discredited him with the navy would have been the best way, however," said old Harding brusquely.

"I'll find a way to do that yet," Mortlake promised.

In the meantime, speculation and wonder had ruled among the occupants of Roy's auto. Everything seemed very much muddled, but one fact stood out clearly, and that was that an attempt had been made to cast suspicion, if not the actual guilt of the robbery, upon Roy.

For what object?

"I have it," cried Peggy suddenly. "If they could have placed Roy under a cloud of suspicion, it would have worked to his discredit with the naval authorities, and might have resulted in our aeroplane being denied a place in the trials. That seems plain enough."

They all agreed that it did. But Jimsy said suddenly: "If that was the case, why didn't they try to make out that I stole it?"

"Because—forgive me Jimsy—you're not Roy. Without him, the tests of the Prescott aeroplane could hardly be conducted. Unless——"

"Unless a certain young person named Peggy Prescott undertook to take charge of them," cried Jess loyally.

"Don't be foolish, Jess," warned Peggy; "but look, here is Mrs. Galloway coming to speak to us."

The farmer's wife approached the automobile, from which none of the party had as yet alighted. She was followed by her husband. Both began apologizing profusely for the questions of the sheriff.

"But land's sakes alive," exclaimed the farmer's wife, "I declar ter goodness, we've bin so flustered thet I don' know no more than a wet hen. My brother, that's Mr. Mortlake, was dead sot on it bein' one of you folks, but I knew that was reediculous."

They hardly knew whether to be angry or to laugh at the woman's blunt frankness. But Roy struck in with a question:

"Wasn't Mr. Mortlake, accompanied by Harding, out here last night?"

"Why, yes," said the woman, with perfect candor. "They stayed quite a while. Harding hed some business with Ike, an'——"

"An' Gene Mortlake said he'd like ter hev a look at yer aeroplane. Yer know he's in thet thar business hisself," volunteered Ike confidentially.

Peggy felt as if she could have groaned aloud. Roy's fears, earlier confided to her, seemed to have been based on a true presentiment. The blue-jowled Mortlake had undoubtedly improved his opportunity to study the Golden Butterfly at close range. The farmer's next words confirmed her.

"Reckon he was powerful interested, too," the farmer went on, "fer he made a lot uv ther nicest droorings you ever seen, an'—why, what's the trouble?"

For Roy, hardly knowing what he intended to do, had jumped from the machine and was sprinting toward the Harding car. But, as he neared it, the old financier, who with Mortlake was already seated in the tonneau, spoke a word in the chauffeur's ear, and the machine dashed off, leaving Roy enraged and nonplussed.

"Too bad, Roy," breathed Peggy, as, rather crestfallen, the lad returned.

"Oh, I don't know, Sis. Even if they hadn't sneaked off like that, and I'd caught the machine, I guess I'd have been like the dog that chased the train. I wouldn't have known what to do with it when I got it."

"But Roy, their flight confirms their guilt!"

"I know, Sis, but what possible way have we to prove it? The rascals have covered up their tracks cleverly."

A sudden thought struck Peggy, and she turned to the farmer.

"Did any of those bills have an identifying mark on it?" she asked.

The farmer shook his head. But Mrs. Galloway had a better memory.

"Why, yes, Ike," she exclaimed; "that twenty-dollar-bill you got frum Si. Giddens fer ther Baldwins. I re'klect thet it hed a big round O in red ink marked on ther back uv it. It was a bit rubbed out, an' hard ter see, but ef you knew it wuz thar an' luked fer it, you could see it plain enough."

After inquiring about the baby, whose thankful mother declared it to be as well as ever, Roy and Jimsy dragged out the Golden Butterfly and boarded it. It had been arranged that the two girls were to spin back to town in the car, the aeroplane following them as closely as possible from above.

As they chugged out of the farm-yard gate and on to the rough road, Peggy's thoughts kept time to the rhythmic pulsations of the motor:

"A-twenty-dollar-bill-with-a-red-round-O. A-twenty-dollar-bill-with-a-red-round-O."
