"When Warwick came into the room where we were awaiting him last evening, did you notice anything in his manner?"

"He did seem rather agitated, now that I think of it. His face was flushed and his voice trembled a bit—just as though he had been quarreling with some one."

Again the secret agent nodded.

"But with whom?" said he. "Not Miss Corbin, I feel sure; and scarcely the old servant woman."

"You think it was with Dr. Morse?" eagerly.

"I don't know. But when Morse was heard entering the house, the girl whispered something to Warwick, rather pleadingly I thought, and he brusquely denied having any intention of doing—whatever it was that she spoke of."

"Humph," said Fuller.

After some hours the train drew into the station at Washington; at once they took a taxi-cab and whirled to a government building. Ashton-Kirk was shown through a spacious suite and into a room where a handsome white-haired gentleman sat at a huge mahogany desk.

"It was kind of you, Mr. Secretary, to put yourself out," said the secret agent.
