[Footnote 2: It must be remembered that the scraps of writing in Felix's hand had not yet been found by the police. The allusions in them to Bartow show him to have been possessed by a jealousy which probably turned to delight when he saw his master smitten down by the object of that master's love and his own hatred. How he came to recognize in the bride of another man the owner of the name he so often saw hovering on the lips of his master, is a question to be answered by more astute students of the laws of perception than myself. Probably he spent much of his time at the loophole on the stairway, studying his master till he understood his every gesture and expression.] [Sidenote: Answered] 12. Notice the following schedule. It has been drawn up after repeated experiments with Bartow and the various slides of the strange lamp which cause so many different lights to shine out in Mr. Adams's study: White light--Water wanted. Green light--Overcoat and hat to be brought. Blue light--Put back books on shelves. Violet light--Arrange study for the night. Yellow light--Watch for next light. Red light--Nothing wanted; stay away. The last was on at the final scene. Note if this fact can be explained by Mr. Adams's account of the same. * * * * * Two paragraphs alone lacked complete explanation. The first, No. 9, was important. The description of the stroke dealt by Mr. Adams's wife did not account for this peculiar feature in Bartow's pantomime. Consulting with the inspector, Mr. Gryce finally approached Mr. Adams and inquired if he had strength to enact before them the blow as he had seen it dealt by his wife. The startled young man looked the question he dared not ask. In common with others, he knew that Bartow had made some characteristic gestures in endeavoring to describe this crime, but he did not know what they were, as this especial bit of information had been carefully held back by the police. He, therefore, did not respond hastily to the suggestion made him, but thought intently for a moment before he thrust out his left hand and caught up some article or other from the inspector's table and made a lunge with it across his body into an imaginary victim at his right. Then he consulted the faces about him with inexpressible anxiety. He found little encouragement in their aspect. "You would make your wife out left-handed," suggested Mr. Gryce. "Now I have been watching her ever since she came into this place, and I have seen no evidence of this." "She is not left-handed, but she thrust with her left hand, because her right was fast held in mine. I had seized her instinctively as she bounded forward for the weapon, and the convulsive clutch of our two hands was not loosed till the horror of her act made her faint, and she fell away from me to the floor crying: 'Tear down the cross and lay it on your brother's breast. I would at least see him die the death of a Christian.'"
