Fyles smiled into the grim face of McBain, and sat back waiting to hear the Scot’s reply. His keen face was alight with expectancy. He wanted this shrewd man’s ideas as well as his facts obtained by observation.

The sergeant’s face was obstinately set. He had already asserted certain convictions about the old pine, and now he detected skepticism in his superior.

“Three times in the last two weeks I have seen the same figure in the shadow of that tree late at night. It hasn’t needed any guessing to locate his identity. Very well, starting with the supposition that the village folk are right, and Charlie Bryant is our man, then his movements about that tree at that hour of the night become more than suspicious. Especially since we know he’s run a big cargo in lately. But while I figger on that tree there’s something else, as I’ve told you. I’ve tracked him into the neighborhood of the old Meeting House and back again to the tree. Now, I’ve seen this play three times, and would have seen the whole of it again last night if that damned coyote of a tenderfoot hadn’t butted in. That’s that, sir.”

Fyles nodded. The older man’s earnestness was not without its weight. But to a man like Fyles, definite proof, or reasonable probabilities, were necessary. Clearing his throat, McBain went on.

“Let’s come to another argument, sir,” he said, setting himself with his arms on the table. “Every man or woman in the place reckons this tough, Charlie Bryant, runs the gang. They can lay their tongues to the names of the men who form the gang. Guess this is the list, and a certain one sure, knowing the men. There’s Pete Clancy, Nick Devereux, both hired men to Miss Seton. There’s Kid Blaney, hired to Bryant himself. There’s Stormy Longton, the gambler and—murderer. Then there’s another I believe to be Macaddo, the train hold-up, and the fellow they call “Holy” Dick. That’s the gang with Bryant at their head, but there may be more of them. I’ve got the names indirectly from the village folk. But this is my point. Never a soul in the village has seen them at work. Never a soul has seen them buy, or sell, or handle, one drop of drink, except what they buy in the saloon to consume. The gang don’t do one single thing to give itself away, and there’s not a man or woman could give them away in the village, except from their talk when they’re drunk.”

The man was making his point, and Fyles remained interested.

“Now, this is the argument, an’ you’ll admit, sir, experience carries a lot of it out. Crooks are scared to death of each other, you know that, sir, better than I do. It’s the basis of their methods. They’ve got to make safe. To do this they have to resort to schemes which hide their identity. They’ll trust each other engaged in the crime because all are involved. But they daren’t trust those who’re under no penalty. What do they do? They’ve got to blind the outside world, the police, and they do it by making a mystery. Now, in this case, the pine is the heart of their mystery. It must give the key to the cache. It must lead us to getting the lot red-handed—running a cargo. That’s what I know and feel, and it’s up to you, sir, to show us the way. I’ve worked on the lines you gave me, sir, and I’ve done all a man can do. I’ve had the whole village watched, and worked inquiry by a farmer outlying the valley. But now we’re plumb at a deadlock till they run another cargo, which I’m calculating, at the rate liquor’s consumed, they’ll soon have to do. Maybe that’ll give us a week or so for fixing our plans. I’ve watched each member of the gang, and we’ve got their movements written down here, from the time we missed that cargo on the trail. Maybe you’ll read my notes on them.”

Fyles took the diary the man held out.

“It’s a tough proposition, McBain,” he said with a sigh, which had no weakening in it. “But I think we’ll make good this time, if only we can get the news of the shipment when it comes along well ahead. Superintendent Jason is in communication with every local police force east, and should get it all right. If we get that, the rest should be easy. Rocky Springs only has three roads, and it’s a small place. I’ve got a pretty wide scheme ready for them when we get word. In the meantime our present work must be to endeavor to locate their cache. That discovered, and left alone, our work will be simple pie. I’ll read these notes now. Then I’m going into the village. Later on I’ve a notion to see just how busy Master Bryant is on his—ranch.”
