"Why can't we get it tonight—or tomorrow at the latest? The Davis laboratory here can do the work. It does laboratory work for all these doctors here."

"It can't do any work for me," objected Greenleaf stubbornly. "Dr. Davis and I aren't on speaking terms, personally or politically. I'll send the stuff down to a laboratory at Charlotte. It will reach there tomorrow morning if I get it off on the midnight train. We can get the telegraphed report on it late tomorrow or the day after."

"All right; I guess that will do," agreed Bristow.

As they started up the steps to the Fulton bungalow, Morley came out to the porch and charged down toward them. His face was convulsed as if by anger or fear. He did not seem to see the two men. Bristow caught him by the arm and put the query:

"Where are you going, Mr. Morley?"

Morley shook off his hand and answered curtly:

"To Washington. I've barely got time to catch my train."

"Don't hurry," Bristow said with a touch of sarcasm. "You're too good at missing trains anyway. Besides, we want to know what you did between midnight and two-ten this morning, and why you failed to tell us this morning that you didn't register at the Brevord until after two."

Morley's face went white.

"There wasn't anything to that," he explained. "I didn't mean to conceal anything. I didn't go anywhere—anywhere specially."
