"You had seen that everything was fast, then?" said Ashton-Kirk, looking at the old woman.

"Yes; every door and every window upon the lower floor and every window overlooking the porch on the second floor. As there was no way by which the house could be entered by any of the other windows we never bothered with them."

"You say Dr. Morse rang for you as you finished locking up?"

"Yes, sir; and I answered. He was in the library, and I was surprised to see that he was dressed as though he meant to go out--perhaps upon a journey. He had on his hat, an overcoat lay across a chair and he was trying to turn a key in the lock of his traveling bag. The key was bent and he had rung for me that I might bring him something to straighten it with. But as he was speaking to me, the lock turned, and he told me that I need not mind."

"You say he was dressed as though to go out. Did he do so?"

"No, sir. I am sure of that, because I went to the hall door and sat upon the step for some time. It was a fine night. So if he had gone out I should have seen him."

"How long did you sit there?"

"About ten minutes. Then I went to prepare the coffee."

"While you sat upon the step did you see or hear anything?"

"I heard Dr. Morse talking."

"With whom?"

"I don't know. I heard a second voice, but not distinctly. I thought it must be Miss Stella or Mr. Warwick."

Here the girl drew a deep, audible breath, and Ashton-Kirk saw the old woman fix her sharp eyes upon her.

"But," resumed Nanon, "Miss Stella tells me that it was not she."

"You went directly from the library to the hall door after speaking to Dr. Morse, you say?"

"Yes, sir."

"Did you close the door while you sat upon the step?"

"No; I left it open, thinking to hear if the doctor rang again."

"No one else was in the library when you spoke to the doctor regarding the key?"

"No one."

"Was there a light in the hallway while you sat at the door?"

"There was."

"Should you have seen any one entering the library?"

"I should. To go into that room he would first have to come through the hall."

"There were no visitors in the house at any time during the evening?"

"No," said Nanon. "I should have heard them ring, even if some one else had admitted them."

Ashton-Kirk turned to the girl.

"It is necessary that I know everything that can be told me as to what took place in the house to-night. So you will pardon a question or two, I know."

She inclined her head in answer to this; but her mouth twitched nervously, and her hands held tightly to the chair upon which she sat.

"Where were you when you learned that Dr. Morse was dead?" proceeded Ashton-Kirk.

"In my sitting-room, where I had gone to read immediately after dinner."

[Ill.u.s.tration: "WHO BROUGHT THE NEWS?"]

"Who brought the news?"

"Nanon. She stood at the foot of the back stairs and called to me."

"Where is your sitting-room?"

"On the second floor at the back; the door was open and I heard her at once."

"Did you hear or see anything else, previous to this?"

"Very early in the evening I saw Drevenoff going to his room on the third floor; I sat facing the doorway and had a view of the stairs."

"He did not come down again?"

"Not until Nanon called him."

"You are quite sure of that?"

"Quite. I should have seen him had he come down."

There was a pause of some length; the secret agent looked from one to the other of the two women, and finally he said to Nanon:

"You say that you are not sure that the second voice you heard in the library was Mr. Warwick's?"

Again came the quick, deep drawn breath from the girl; and again the gray eyes of the old woman sought her face. At the same time she replied:

"I heard a voice. Whose it was, I cannot say."

There was another pause; then he turned to Miss Corbin.

"At all events," said he, smoothly, "I should like to speak to him."

She arose a trifle unsteady.

"I am sorry," she said in a low voice, "but I am afraid that is impossible, just now."
