“The seven o’clock train from Chicago?” the clerk asked in a guarded voice.

“It came in at 10:30, as expected? Oh, at 10:10! Thank you.” He hung up the receiver and opened the door to pass a word with Rowan as he came out of the president’s office.

“They’ve wired that the Elizabethan Age couldn’t get beyond Boston, Rowan,” he cried curiously.

“The —— —— —— hooker!” The dock superintendent had gone strangely white; for the imperceptible fraction of an instant his eyes dimmed with fear, as he stared into the wondering face of the clerk, but he recovered himself quickly, spat offensively, and slammed the door as he went out. Rentland stood with clenching hands for a moment; then he glanced at the clock and hurried to the entrance of the outer office. The elevator was just bringing up from the street a red-haired, blue-gray-eyed young man of medium height, who, noting with a quick, intelligent glance the arrangement of the offices, advanced directly toward President Welter’s door. The chief clerk stepped forward quickly.

“You are Mr. Trant?”

“Yes.”

“I am Rentland. This way, please.” He led the psychologist to the little room behind the files, where he had telephoned the moment before.

“Your wire to me in Chicago, which brought me here,” said Trant, turning from the inscription “Chief Clerk” on the door to the dogged, decisive features and wiry form of his client, “gave me to understand that you wished to have me investigate the disappearance, or death, of two of your dock scale checkers. I suppose you were acting for President Welter—of whom I have heard—in sending for me?”

“No,” said Rentland, as he waved Trant to a seat. “President Welter is certainly not troubling himself to that extent over an investigation.”

“Then the company, or some other officer?” Trant questioned, with increasing curiosity.
