"Sit down," he rapped out. "That isn't 'bill of lading'; it's 'building and loan.'"

Hallock dragged the one vacant chair into the circle illuminated by the shaded desk-electric, and sat on the edge of it, with his hands on his knees. "Well?" he said, in the grating voice that was so curiously like the master-mechanic's.

"We can cut out the details," this from the man who, under other conditions, would have gone diplomatically into the smallest details. "Some years ago you were the treasurer of the Mesa Building and Loan Association. When the association went out of business, its books showed a cash balance in the treasury. What became of the money?"

Hallock sat as rigid as a carved figure flanking an Egyptian propylon, which his attitude suggested. He was silent for a time, so long a time that Lidgerwood burst out impatiently, "Why don't you answer me?"

"I was just wondering if it is worth while for you to throw me overboard," said the chief clerk, speaking slowly and quite without heat. "You are needing friends pretty badly just now, if you only knew it, Mr. Lidgerwood."

The cool retort, as from an equal in rank, added fresh fuel to the fire.

"I'm not buying friends with concessions to injustice and crooked dealing," Lidgerwood exploded. "You were in the railroad service when the money was paid over to you, and you are in the railroad service now. I want to know where the money went."

"It is none of your business, Mr. Lidgerwood," said the carved figure with the gloomy eyes that never blinked.

"By heavens! I'm making it my business, Hallock! These men who were robbed say that you are an embezzler, a thief. If you are not, you've got to clear yourself. If you are, you can't stay in the Red Butte service another day: that's all."

Again there was a silence surcharged with electric possibilities. Lidgerwood bit the end from a cigar and lost three matches before he succeeded in lighting it. Hallock sat perfectly still, but the sallow tinge in his gaunt face had given place to a stony pallor. When he spoke, it was still without anger.
