"Bartow was standing face to face with the assailant. In imitating him, especially in his unreasoning state of mind, he would lift the arm opposite to the one whose action he mimics, which, in this case, would be the assailant's right. Try, for the moment, to mimic my actions. See! I lift this hand, and instinctively (nay, I detected the movement, sir, quickly as you remembered yourself), you raise the one directly opposite to it. It is like seeing yourself in a mirror. You turn your head to the right, but your image turns to the left."

Mr. Gryce's laugh rang out in spite of himself. He was not often caught napping, but this woman exercised a species of fascination upon him at times, and it rather amused than offended him, when he was obliged to acknowledge himself defeated.

"Very good! You have proved your point quite satisfactorily; but what conclusions are to be drawn from it? That the man was not left-handed, or that he was not standing in the place you have assigned to him?"

"Shall we go against the doctors? They say that the blow was a left-handed one. Mr. Gryce, I would give anything for an hour spent with you in Mr. Adams's study, with Bartow free to move about at his will. I think we would learn more by watching him for a short space of time than in talking as we are doing for an hour."

It was said tentatively, almost timidly. Miss Butterworth had some sense of the temerity involved in this suggestion even if, according to her own declaration, she had no curiosity. "I don't want to be disagreeable," she smiled.

She was so far from being so that Mr. Gryce was taken unawares, and for once in his life became impulsive.

"I think it can be managed, madam; that is, after the funeral. There are too many officials now in the house, and——"

"Of course, of course," she acceded. "I should not think of obtruding myself at present. But the case is so interesting, and my connection with it so peculiar, that I sometimes forget myself. Do you think"—here she became quite nervous for one of her marked self-control—"that I have laid myself open to a summons from the coroner?"

Mr. Gryce grew thoughtful, eyed the good lady, or rather her folded hands, with an air of some compassion, and finally replied:

"The facts regarding this affair come in so slowly that I doubt if the inquest is held for several days. Meanwhile we may light on those two young people ourselves. If so, the coroner may overlook your share in bringing them to our notice."
