"It's just as well, I guess," said the main-line superintendent carelessly. "I probably shouldn't get it straight anyway. It's a rather horrible affair, though, I believe. There is another man mixed up in it—the man whom she is always asking if Hallock has killed. Curiously enough, she never names the other man, and there have been a good many guesses. I believe your head boiler-maker, Gridley, has the most votes. He's been seen with her here, now and then—when he's on one of his 'periodicals.' By Jove! Lidgerwood, I don't envy you your job over yonder in the Red Desert a little bit.... But about the consolidation of the yards here: I got a telegram after I wired you, making it necessary for me to go west on main-line Twenty-seven early in the morning, so I stayed up to talk this yard business over with you to-night."

It was well along in the small hours when the roll of blue-print maps was finally laid aside, and Leckhard rose yawning. "We'll carry it out as you propose, and divide the expense between the two divisions," he said in conclusion. "Frisbie has left it to us, and he will approve whatever we agree upon. Will you go up to the hotel with me, or bunk down here?"

Lidgerwood said he would stay with his car; or, better still, now that the business for which he had come to Copah was despatched, he would have the roundhouse night foreman call a Red Butte Western crew and go back to his desert.

"We are in the thick of things over on the jerk-water just now," he explained, "and I don't like to stay away any longer than I have to."

"Having a good bit of trouble with the sure-shots?" asked Leckhard. "What was that story I heard about somebody swiping one of your switching-engines?"

"It was true," said Lidgerwood, adding, "But I think we shall recover the engine—and some other things—presently." He liked Leckhard well enough, but he wished he would go. There are exigencies in which even the comments of a friend and well-wisher are superfluous.

"You have a pretty tough gang to handle over these," the well-wisher went on. "I wouldn't touch a job like yours with a ten-foot pole, unless I could shoot good enough to be sure of hitting a half-dollar nine times out of ten at thirty paces. Somebody was telling me that you have already had trouble with that fellow Rufford."

"Nobody was hurt, and Rufford is in jail," said Lidgerwood, hoping to kill the friendly inquiry before it should run into details.

"Oh, well, it's all in the day's work, I suppose, which reminds me: my day's work to-morrow won't amount to much if I don't go and turn in. Good-night."

When Leckhard was gone, Lidgerwood climbed the stair in the station building to the despatcher's office and gave orders for the return of his car to Angels. Half an hour later the one-car special was retracing its way westward up the valley of the Tumbling Water, and Lidgerwood was trying to go to sleep in the well-appointed little state-room which it was Tadasu Matsuwari's pride to keep spick and span and spotlessly clean. But there were disturbing thoughts, many and varied, to keep him awake, chief among them those which hung upon the dramatic midnight episode with the demented woman for its central figure. Through what dreadful Valley of Humiliation had she come to reach the abysmal depths in which the one cry of her soul was a cry for vengeance? Who was the unnamed man whom Hallock had promised to kill? How much or how little was this tragedy figuring in the trouble storm which was brooding over the Red Desert? And how much or how little would it involve one who was anxious only to see even-handed justice prevail?
