"Well, you know he wanted to be superintendent of this road. He kept the wires to New York hot for a week after he found out that the P. S-W. was in control. He missed it, and you naturally took it over his head—at least, maybe that's the way he looks at it."

"Take it for granted and get to the point," urged Lidgerwood, always impatient of preliminary bush-beating.

"There isn't any point, if you don't see any," said McCloskey stubbornly. "But I can tell you how it would strike me, if I had to be wearing your shoes just now. You've got a man for your chief clerk who has kept this whole town guessing for two years. Some say he isn't all to the bad; some say he is a woman-killer; but they all agree that he's as spiteful as an Indian. He wanted your job: supposing he still wants it."

"Stick to the facts, Mac," said the superintendent. "You're theorizing now, you know."

"Well, by gravels, I will!" rasped McCloskey, pushed over the cautionary edge by Lidgerwood's indifference to the main question at issue. "What I know don't amount to much yet, but it all leans one way. Hallock puts in his daytime scratching away at his desk out there, and you'd think he didn't know it was this year. But when that desk is shut up, you'll find him at the roundhouse, over in the freight yard, round the switch shanties, or up at Biggs's—anywhere he can get half a dozen of the men together. I haven't found a man yet that I could trust to keep tab on him, and I don't know what he's doing; but I can guess."

"Is that all?" said Lidgerwood quietly.

"No, it isn't! That switch-engine dropped out two weeks ago last Tuesday night. I've been prying into this locked-up puzzle-box every way I could think of ever since. Hallock knows where that engine went!"

"What makes you think so?"

"I'll tell you. Robinson, the night-crew engineer, was a little late leaving her that night. His fireman had gone home, and so had the yardmen. After he had crossed the yard coming out, he saw a man sneaking toward the shifter, keeping in the shadow of the coal-chutes. He was just curious enough to want to know who it was, and he made a little sneak of his own. When he found it was Hallock, he went home and thought no more about it till I got him to talk."

Lidgerwood had gone back to the pencil and the blotting-pad and the making of squares.
