"Not until the night of his death. Then she was called into the library, as she stated, and in some manner the thing came out. I talked with her as to this later before leaving for Washington, but she could give no clear account of it. However, I think he uttered some sort of a taunt, as was his habit, and she replied in kind. The meaning of the drawings sent by Okiu had gradually dawned upon her, it seems, and she had concluded that the suspense which he suffered because of them was a sort of retribution. She must have put this thought into words, and in an instant the truth was out. In a rage he took a revolver from his desk. She did not know whether it was merely an attempt to frighten her or no; however, she feared for her life and snatched at the weapon. It exploded and he fell back into the chair.
"Yes; it was old Nanon who killed Morse. She concealed the revolver upon her person and went to the front door, where she sat for some time, as she told in her first story. She was calm and self-contained—she felt that she had done no wrong."
"And so she concluded it would be best to 'find the body' when she brought in the coffee?"
"Yes; and while she was engaged with this Drevenoff stole down the front stairs, admitted his woman confederate to the room back of the library—and discovered the dead body of Dr. Morse. Then followed the fear-filled search; the approach of Warwick added to their fright. They evidently carried a pocket torch, which accounts for the library being dark when Warwick entered. Then the girl, Julia, made an effort to escape with the bag; and while Warwick was in pursuit of her, Drevenoff crept back to his room."
Fuller nodded slowly.
"Yes," said he, "it could very easily have been that way. But tell me this: The old woman knew all the time that she was responsible for the death of Morse; so why did she manifest so much uneasiness whenever Warwick was mentioned in the matter?"
"She was alarmed at his disappearance because she was shrewd enough to know that this would attract attention toward him. There were two reasons for this. She felt kindly toward Warwick, and so disliked his being falsely accused. Then, if he was arrested, she would be forced to confess the truth to save him. She had these things in mind when she withheld the fact that she had seen Morse strike the young man.
"She claimed to have heard voices in the library while she sat upon the step. Now, Dr. Morse was dead at that time and none of the others had yet gone into the room.
"The voices were a fiction. She thought to mislead the police by the invention. Or perhaps she really thought she heard them; I did not question her very closely upon this point. A woman like that is apt to see and hear things which do not exist. Witness her suspicion of Miss Corbin. She fancied that for some dark reasons the girl was making an effort to have the crime fixed upon Warwick, while professing to love him. That Miss Corbin had been long under the influence of Dr. Morse made this idea, to Nanon's mind, not only possible, but probable.
"This thought grew upon the old woman until it seemed she could scarcely think of anything else. Her constant espionage finally attracted Miss Corbin's attention, as she told me at the Tillinghast after you left the room. In her turn she began to suspect and watch. With the feeling that the scapular should be well hidden, Nanon placed it in one of the candlesticks, cunningly calculating that as the article had once been searched, it would be passed by thereafter."
