The colonel was thoroughly enjoying himself, for he had put aside, in the perusal of Walton, all thoughts of the murder and its many complications, when there came another interruption. This time it was a ring of his room telephone.

"There's a gentleman downstairs asking for you," came the word in response to his answer to the summons.

"Who is it?

"Says I'm to tell you he's Mr. Young."

"Oh, yes, Jack Young--send him up." The colonel closed the book with a sigh of regret.

"No use trying to read Izaak now," he murmured. "It would be a sacrilege. I'll have to wait a bit. Wonder what Jack wants. Ah, come in!" he called, as a discreet knock sounded on the half-opened door.

"Trouble?"

"Not yet, Colonel, though there may be. Do you want me to follow King out of town?"

"Of course. Wherever he goes. Stick to him like a leech," and the detective indicated a chair to his visitor. Jack Young was one of the Ashley Agency's most trusted lieutenants.

"I sent for you to have you shadow King," said the detective in a low voice, seeing to it that the door was closed, "because I think we can get something out of him."

"Not a confession, surely!" exclaimed Young.

"Well, if he gets drunk enough, yes. But not the kind of confession that would be any use to us. What a man babbles when the wine is in and the wit is out, wouldn't be much use in a court of law. But if you can get him to tell anything about where he got that queer coin--the one that used to be in Mrs. Darcy's collection--so much to the good.

But be foxy about it, Jack."

"I will! What I came to see about is whether you want me to follow him out of town. He's been cutting a pretty wide swath since he got out on bail, and he's been having some pretty sporty times."

"And you've been with him; is that it?"

"To the best of my ability, yes," admitted Jack, as he patted Chet, when the dog, that evidently had met him before, slid over to have his ears pulled.

"I have great faith in your ability, Jack. The point is to stick to King. You managed to make friends with him?"

"That wasn't hard. But I'll need a little money if I'm to keep up his pace. That's why I came to you."

"Perfectly right, Jack. Mason so thoroughly believes in the innocence of Darcy, and he sticks by his daughter's engagement so well, that he'd supply twice as much cash as was necessary to sift this to the bottom.

So here's some to enable you to keep up to King's pace."

"Of course it's none of my business, Colonel, but I'd like to know a little bit about how the wind blows. Do you really suspect him of the murder?"

"Jack, I don't know!" was the frank answer, as Chet went back to his place by the gas log. "His having that odd coin was what put me on his trail again, and I sent for you to shadow him, as I had too many other irons in the fire. And you've done well. I guess there isn't much that Harry has done since that night about a week ago, when I saw him in the Homestead, that you don't know about."

"I guess not, Colonel."

"But, with it all, I'm not much nearer than I was at first."

"How about Spotty?"

"He won't say a word."

"You tried the third degree on him, of course?"

"I--er--I did and I didn't," the colonel answered, lamely. "You see, you can't go too far with a man when he has saved your life."

"But he may know all about it."

"Possibly."

"How about young Darcy?"

The colonel did not answer at once. It was not until he had gone to a closet and taken from it a package which he placed on a tabarette, on which, near him, rested a box of cigars, that he spoke. Then he said:

"If I could find out why Singa Phut used this watch I'd be in a better position to answer," and from the package the detective took the timepiece which he had kept after Donovan had given it to him to examine.

"You mean you're not sure about Darcy?"

"Well, I thought I was. At first I had my doubts. Then, when I had looked over the ground and talked with Miss Mason and him, I was willing to take up his case just because I believed he had nothing to do with the murder."

The colonel, who had taken the watch from some tissue paper in which it was wrapped, laid it down on the low stool, and turned his attention to his visitor. Chet with a whine and stretch, indicating that he was warmed and rested, and would not object to a little play, walked slowly over toward the colonel.

"But," went on the detective, "since the finding of the electric wires running to Darcy's desk--Jack, I tell you what it is. You helped me out wonderfully on that robbery of the Chatham bank, when the cashier ran some wires to the time lock and had it open five hours ahead of time, I wish you'd come and have a look at those wires with me. Maybe you could give me a hint that would clear up some of the doubt I have regarding Darcy."

"All right, Colonel, I'll come. But I think I'd better follow King now. He's got a date with Larch, the hotel keeper, and there may be something in it."

"Oh, go by all means! The wires will keep. Here, I'll give you an idea about how they run," and the colonel drew a sort of diagram of the jewelry store, indicating the showcase where the hidden wires had been found, explaining to his man the effect on the young woman clerk who had been shocked.

Jack Young studied the diagram carefully and shook his head. The colonel, meanwhile, sat back and waited. Chet was worrying the tissue paper in which the Indian's watch was wrapped.

"Well, Colonel, I'll tell you what it is," said Jack, after a series of questions, "I'd have to see the place to get at any right idea of it.

Not to cast any aspersions on your ability as an artist, I can't just make out how the wires run, from this sketch," and he smiled, after having studied the drawings for perhaps ten minutes.

"Don't blame you a bit!" laughed the colonel. "I never was much on pencil work. But now you follow Harry King. If you need more money, come to me," he added as he handed over a roll of bills. "And then we'll have to go at those wires. I'm not so sure--"

The colonel's remarks were interrupted by peculiar actions on the part of Chet. The little animal appeared to have gotten something into his mouth which bothered him. He was whining and pawing at his jaws.

"Look at the dog, Colonel!" exclaimed Jack. "Look!"

"Gad! he's got hold of the Indian's watch!" cried the detective. "He's been worrying it as he would a bone, and he's got it in his mouth and can't get it out! Easy there! don't touch it!" came the sharp command, as Jack Young took a step forward, evidently with the intention of helping the distressed animal.

"What's the matter, Colonel?" asked Jack. "You don't want to see the dog suffer, do you?"

"No, but--there, he's got it out himself!"

With an effort the dog had pawed from his mouth the watch, which, being rather large and of peculiar shape, had for some time, been stuck in his jaws. It rolled out on the floor, and the colonel stooped to pick it up. But Jack noticed that his chief used a wad of the tissue paper with which to handle the timepiece, which was no longer ticking.

"What's the matter--'fraid of soiling your hands?" asked Jack with a laugh.

"Well, yes, in a way--"

"Look at the dog's mouth! It's bleeding!" cried Jack, pointing.
