It was the draftsman's turn to hesitate.

"I'm prejudiced," he confessed at length. "I know Gridley; he is a worse man than a good many people think he is--and not so bad as some others believe him to be. If he thought you, or Benson, were getting in his way--up at the house, you know----"

Lidgerwood smiled.

"You don't want him for a brother-in-law; is that it, Fred?"

"I'd cheerfully help to put my sister in her coffin, if that were the alternative," said Dawson quite calmly.

"Well," said the superintendent, "he can easily prove an alibi, so far as this wreck is concerned. He went east on 202 yesterday. You knew that, didn't you?"

"Yes, I knew it, but----"

"But what?"

"It doesn't count," said the draftsman, briefly. Then: "Who was the other man, the man who came west on 205?"

"I hate to say it, Fred, but it was Hallock. We saw the wreck, all of us, from the back platform of my car. Williams had just pulled us out on the old spur. Just before Cranford shut off and jammed on his air-brakes, a man ran down the track, swinging his arms like a madman.

Of course, there wasn't the time or any chance for me to identify him, and I saw him only for the second or two intervening, and with his back toward us. But the back looked like Hallock's; I'm afraid it was Hallock's."

"But why should he weaken at the last moment and try to stop the train?"

queried Dawson.

"You forget that it was the special, and not the pa.s.senger, that was to be wrecked."

"Sure," said the draftsman.

"I've told you this, Fred, because, if the man we saw were Hallock, he'll probably turn up while you are at work; Hallock, with Judson at his heels. You'll know what to do in that event?"

"I guess so: keep a sharp eye on Hallock, and make Judson hold his tongue. I'll do both."

"That's all," said the superintendent. "Now I'll have Bradford pull us up on the spur to give you room to get your baby crane ahead; then you can pull down and let us out."

The shifting took some few minutes, and more than a little skill. While it was in progress Lidgerwood was in the service-car, trying to persuade the young women to go to his state-room for a little rest and sleep on the return run. In the midst of the argument, the door opened and Dawson came in. From the instant of his entrance it was plain that he had expected to find the superintendent alone; that he was visibly and painfully embarra.s.sed.

Lidgerwood excused himself and went quickly to the embarra.s.sed one, who was still anchoring himself to the door-k.n.o.b. "What is it, Fred?" he asked.

"Judson: he has just turned up, walking from Little b.u.t.te, he says, with a pretty badly bruised ankle. He is loaded to the muzzle with news of some sort, and he wants to know if you'll take him with you to An--" The draftsman, facing the group under the Pintsch globe at the other end of the open compartment, stopped suddenly and his big jaw grew rigid. Then he said, in an awed whisper, "G.o.d! let me get out of here!"

"Tell Judson to come aboard," said Lidgerwood; and the draftsman was twisting at the door-k.n.o.b when Miriam Holcombe came swiftly down the compartment.

"Wait, Fred," she said gently. "I have come all the way out here to ask my question, and you mustn't try to stop me: are you going to keep on letting it make us both desolate--for always?" She seemed not to see or to care that Lidgerwood made a listening third.

Dawson's face had grown suddenly haggard, and he, too, ignored the superintendent.

"How can you say that to me, Miriam?" he returned almost gruffly. "Day and night I am paying, paying, and the debt never grows less. If it wasn't for my mother and Faith ... but I must go on paying. I killed your brother----"

"No," she denied, "that was an accident for which you were no more to blame than he was: but you are killing me."

Lidgerwood stood by, man-like, because he did not know enough to vanish.

But Miss Brewster suddenly swept down the compartment to drag him out of the way of those who did not need him.

"You'd spoil it all, if you could, wouldn't you?" she whispered, in a fine feminine rage; "and after I have moved heaven and earth to get Miriam to come out here for this one special blessed moment! Go and drive the others into a corner, and keep them there."

Lidgerwood obeyed, quite meekly; and when he looked again, Dawson had gone, and Miss Holcombe was sobbing comfortably in Eleanor's arms.

Judson boarded the service-car when it was pulled up to the switch; and after Lidgerwood had disposed of his pa.s.sengers for the run back to Angels, he listened to the ex-engineer's report, sitting quietly while Judson told him of the plot and of the plotters. At the close he said gravely: "You are sure it was Hallock who got off of the night train at Silver Switch and went up the old spur?"

It was a test question, and the engineer did not answer it off-hand.

"I'd say yes in a holy minute if there wasn't so blamed much else tied on to it, Mr. Lidgerwood. I was sure, at the time, that it was Hallock; and besides, I heard him talking to Flemister afterward, and I saw his mug shadowed out on the window curtain, just as I've been telling you.

All I can say crosswise, is that I didn't get to see him face to face anywhere; in the gulch, or in the office, or in the mine, or any place else."

"Yet you are convinced, in your own mind?"

"I am."

"You say you saw him and Flemister get on the hand-car and pump themselves down the old spur; of course, you couldn't identify either of them from the top of the ridge?"

"That's a guess," admitted the ex-engineer frankly. "All I could see was that there were two men on the car. But it fits in pretty good: I hear 'em plannin' what-all they're going to do; foller 'em a good bit more'n half-way through the mine tunnel; hike back and hump myself over the hill, and get there in time to see two men--_some_ two men--rushin'

out the hand-car to go somewhere. That ain't court evidence, maybe, but I've seen more'n one jury that'd hang both of 'em on it."

"But the third man, Judson; the man you saw beating with his fists on the bulkhead air-lock: who was he?" persisted Lidgerwood.

"Now you've got me guessin' again. If I hadn't been dead certain that I saw Hallock go on ahead with Flemister--but I did see him; saw 'em both go through the little door, one after the other, and heard it slam before the other dub turned up. No," reading the question in the superintendent's eye, "not a drop, Mr. Lidgerwood; I ain't touched not, tasted not, n'r handled not--'r leastwise, not to drink any," and here he told the bottle episode which had ended in the smashing of Flemister's sideboard supply.

Lidgerwood nodded approvingly when the modest narrative reached the bottle-smashing point.

"That was fine, John," he said, using the ex-engineer's Christian name for the first time in the long interview. "If you've got it in you to do such a thing as that, at such a time, there is good hope for you. Let's settle this question once for all: all I ask is that you prove up on your good intentions. Show me that you have quit, not for a day or a week, but for all time, and I shall be only too glad to see you pulling pa.s.senger-trains again. But to get back to this crime of to-night: when you left Flemister's office, after telephoning Goodloe, you walked down to Little b.u.t.te station?"

"Yes; walked and run. There was n.o.body there but the bridge watchman.

Goodloe had come on up the track to find out what had happened."

"And you didn't see Flemister or Hallock again?"

"No."

"Flemister told us he got the news by 'phone, and when he said it the wreck was no more than an hour old. He couldn't have walked down from the mine in that time. Where could he have got the message, and from whom?"

Judson was shaking his head.

"He didn't need any message--and he didn't get any. I'd put it up this way: after that rail-joint was sprung open, they'd go back up the old spur on the hand-car, wouldn't they? And on the way they'd be pretty sure to hear Cranford when he whistled for Little b.u.t.te. That'd let 'em know what was due to happen, right then and there. After that, it'd be easy enough. All Flemister had to do was to rout out his miners over his own telephones, jump onto the hand-car again, and come back in time to show up to you."

Lidgerwood was frowning thoughtfully.

"Then both of them must have come back; or, no--that must have been your third man who tried to flag Cranford down. Judson, I've got to know who that third man is. He has complicated things so that I don't dare move, even against Flemister, until I know more. We are not at the ultimate bottom of this thing yet."

"We're far enough to put the handcuffs onto Mr. Pennington Flemister any time you say," a.s.serted Judson. "There was one little thing that I forgot to put in the report: when you get ready to take that missing switch-engine back, you'll find it _choo-chooin'_ away up yonder in Flemister's new power-house that he's built out of boards made from Mr.
