"And receiving tellers," put in Bristow quickly, "sometimes need money—need it to make good other money they have 'borrowed' from the bank. How did you find this out?"

"He told me when I met him at Number Five after leaving you this afternoon."

"Was he still there then?"

"Yes. It seems that Miss Fulton refused at first to see him. When she did see him, it was for only a minute or two. He was very much agitated when he came from her room."

"There's another thing," added Bristow. "Morley has two hours of last night to account for. He told us he missed the midnight train and went to the Brevord to spend the night. As a matter of fact, he registered at the Brevord a little after two o'clock this morning."

The chief's jaw dropped.

"How do you know that?"

"I called up the Brevord and got the information from the clerk."

"That settles it, then," Greenleaf said, his jaw set. "That young man will have to remain with us for a while."

"Yes; quite properly."
