is a thief. In fact, I have a plan. We might try it.”

“What is your plan?” asked Sandy.

“We’ll lay a trap for him. Between us we can scrape up a little roll of money, and we’ll use that as bait. I’ll pull it out of my pocket when he’s looking, and pretend I’m counting it.”

“Yes, yes! Go on.”

“I’ll return the money to the inside pocket of my coat while he’s still watching me. At night, when he comes into the room, I’ll throw my coat carelessly over a chair.”

“Look here,” objected Sandy, a wry smile on his face, “I don’t think we have fifty dollars between us. Hardly an impressive roll, is it?”

Dick grinned. “I can easily remedy that.”

As he spoke, he pulled from his pocket a number of old envelopes, containing letters, wadded them together and then began wrapping crisp new bills around them. With the acquisition of the bank notes Toma and Sandy gave him, the dummy had grown to noble proportions. The boys laughed gleefully over the subterfuge.

A short time later, returning to the house, Dick awaited his opportunity. Frischette was nowhere to be seen, when first they entered, but presently a noise at the back attracted their attention and immediately afterward Frischette came through the door, leading into the kitchen, carrying a box under his arm.

Dick and Sandy exchanged significant glances. Both recalled what Toma had told them regarding that box. Also they observed the inexplicable change that had come over their host. His animation and vivacity were gone. From under their shaggy brows his dark eyes darted glances from right to left—the look of a maniac or insane person. Without even a nod, he passed by the three boys and entered his own room.

“Got ’em again,” whispered Sandy, much taken aback. “Not a very good time for the working out of our plan, is it? He’s deeply engrossed in that mysterious box by this time.”

“We’d better try it out on him tomorrow,” decided Dick. “He’ll be in there several hours, and it will probably take him another hour to find a new hiding place for his precious treasure chest. It’s getting late now. We ought to be in bed.”

The boys went over and sat down on a long bench near the fireplace and began idly to take mental inventory of the room. Bear skins hung from the wall. In the center of the room stood a long rough board table, covered with a somewhat frayed and tattered cloth. Above the mantel were several firearms of various caliber and design.

Suddenly, Sandy leaned forward and clapped Dick on the knee.

“Dick, I have an idea. Just for the fun of it, let’s follow the old rascal and find out where he hides that box.”

Dick looked at the other dubiously.

“Well,” he hesitated. “I don’t know. It seems like meddling to me—prying into something that doesn’t concern us.”

“Wait a moment, Dick. Is it really meddling? For the sake of argument, suppose that box contained Dewberry’s poke and money. We already have a suspicion that such may be the case. Why wouldn’t we be justified in following him, when he leaves his room, and attempt to find where he hides the box?”

“But surely you wouldn’t open it?”

“Why not? I don’t think I would have any scruples about that. Remember you are dealing with a crook.”

“Are we?” argued Dick. “What makes you so sure? We have proved nothing against him. Neither has Corporal Rand. He may be entirely innocent.”

Sandy lifted his shoulders in a gesture of impatience.

“I’m afraid you’d make a poor detective. You’re too honest, too cautious.” He paused, looked up and grinned. “Can you picture a case-hardened police officer or the average sleuth passing up such an opportunity? Candidly now?”

Dick was forced to admit that his chum was right. “I’ll grant you,” he smiled, “that no one, working on a case like this, ought to have trouble with his conscience.”

“No, he shouldn’t. As long as we are in the business, we might as well conduct ourselves like real detectives.”

“All right, you can have your way this time. We’ll follow Frischette. We’ll even pry open the box if you say so.”

A shadow flickered across Sandy’s forehead.

“But supposing the box is locked. There’s a possibility that hadn’t occurred to me. We’d be in a difficult position, wouldn’t we, if we broke it open and found that there was nothing there to incriminate him? Frischette would see that the box had been tampered with. He’d guess that one of us, you, Toma or I, had opened it, or possibly he might suspect Fontaine or Le Sueur.”

“If the box is locked,” reasoned Dick, “there is a key to open it.”

“Yes—and he probably carries it around his neck. Fine chance we’d have getting it from him.”

Their whispered conversation was interrupted at this juncture by the creak of a door opening, and the sound of footsteps along the floor. Startled, the boys looked up, just as Frischette came into the room where they were, the box under his arm. He had come sooner than they had expected. Again the boys noticed his strange behaviour. Some sudden impulse induced Dick to accost him.

“Mr. Frischette, may I trouble you for a moment.” He attempted to control the quaver in his voice. “We—Sandy, Toma and I—have been wondering about our bill. If you don’t mind, we’d like to pay you.”

Frischette’s face recovered some of its former cheerfulness.

“Ah, monsieurs, surely you are not to go so soon. Did you not tell me zat you stay here for three, four day yet. I will be ver’ sorry ef you go now.”

“But we have no intention of going now,” Dick enlightened him. “We merely wish to pay you in advance.”

The Frenchman’s dark face brightened. He watched Dick reach in his pocket and pull forth a huge roll of bills. At sight of it, his eyes gleamed and sparkled with envy.

“If you weesh, monsieur. But et ees not necessary. Ze amount ees twenty dollars for ze three of you.”

Dick fondled the heavy roll, slowly peeling off the required amount. He was watching the roadhouse keeper and noticed with satisfaction the effect the money had upon him. To his surprise, Frischette said:

“Ees not monsieur leetle careless to carry roun’ so ver’ much money? Are you not afraid zat thief will take et or else you lose et from your pocket?”

Dick pooh-poohed the idea, laughed, and with a sly look at Sandy, thrust the roll carelessly in the inside pocket of his coat. Frischette followed every move. His eyes seemed to burn into Dick’s pockets. A look of greed so transformed his features that for a time Dick could scarcely believe that this was the genial, obliging host of the previous afternoon.

When he had received the twenty dollars, Frischette had found it necessary to put down the square box, containing his treasure. He had placed it on the table at his elbow with his right arm flung out across it. Not once did he move from this position. While Dick was carrying out his part of the prearranged plan, Sandy also was busy. He moved to the opposite side of the table, in order to get a better view of the box. What he wanted to find out was whether or not it was locked.

Not until Frischette was in the act of picking up the box, preparing to go, was Sandy able to determine about the lock. A key would not be necessary. The small but formidable-looking chest could easily be opened. Sandy smiled to himself.

All that remained to be done now, he reasoned, was to follow Frischette and learn where he kept his treasure. Then, when the opportunity
