Morgan became alert. It was possible that a man like Cole, with a large list of properties under his management, might be somewhat vague in his recollection of the names of a few of his tenants. This case was different. The Atwoods, according to the girl's story, had sub-leased their apartment quite recently, presumably with the agent's sanction. The present excitement should naturally have recalled this matter to Cole's mind—should even have concentrated his thoughts upon the names and characteristics of every tenant in this particular building. Cole's unfamiliarity with the name of Atwood, therefore, seemed peculiar.

At this moment a boy entered with a large volume. Laying it on Cole's desk, the boy passed quietly out of the office. Cole glanced at the index and then turned over certain pages in the book.

"We have no Atwood in that house," he declared, finally, looking up at Morgan. "You must have made a mistake."

Before replying, Morgan pulled out a small notebook and spread it open on his knee, ready for use. He also extracted a pencil from his vest pocket. Glancing at the point to see that it was in working condition, he turned to Cole with the question, "Who does occupy the third floor south in that house?"

"A family named Crocker."

"Full name, please."

"Joseph Crocker. He rented that apartment one year ago the first of this month," stated Cole, after further reference to the book.

Morgan jotted this down in his notebook.

"You haven't heard that Mr. Crocker sub-leased his flat?" inquired Morgan.

"No," replied Cole, positively. "I would be sure to know about it, too. A transaction of that kind must be put through and reported in this office."
