He was not angry: fellow-feeling for my disappointment made him unusually gentle. His voice was therefore very kind when he said: "Madam, if you know it to have been a man, say so. I do not wish to waste my time." "I do not know it." "Very well, then, I will tell you why I think my supposition true. Mr. Knollys, as you probably have already discovered, is a man with a secret passion for vivisection." "Yes, I have discovered that." "It is known to his family, and it is known to a very few others, but it is not known to the world at large, not even to his fellow-villagers.' "I can believe it," said I. "His sisters, who are gentle girls, regard the matter as the gentle-hearted usually do. They have tried in every way to influence him to abandon it, but unsuccessfully so far, for he is not only entirely unamenable to persuasion, but has a nature of such brutality he could not live without some such excitement to help away his life in this dreary house. All they can do, then, is to conceal these cruelties from the eyes of the people who already execrate him for his many roughnesses and the undoubted shadow under which he lives. Time was when I thought this shadow had a substance worth our investigation, but a further knowledge of his real fault and a completer knowledge of his sisters' virtues turned my inquiries in a new direction, where I have found, as I have told you, actual reason for arresting Mother Jane. Have you anything to say against these conclusions? Cannot you see that all your suspicions can be explained by the brother's cruel impulses and the sisters' horror of having those impulses known?" I thought a moment; then I cried out boldly: "No, I cannot, Mr. Gryce. The anxiety, the fear, which I have seen depicted on these sisters' faces for days might be explained perhaps by this theory; but the knot of crape on the window-shutter, the open Bible in the room of death--William's room, Mr. Gryce,--proclaim that it was a human being, and nothing less, for whom Lucetta's sobs went up." "I do not follow you," he said, moved for the first time from his composure. "What do you mean by a knot of crape, and when was it you obtained entrance into William's room?" "Ah," I exclaimed in dry retort; "you are beginning to see that I have something as interesting to report as yourself. Did you think me a superficial egotist, without facts to back my assertions?" "I should not have done you that injustice." "I have penetrated, I think, deeper than even yourself, into William's character. I think him capable--But do satisfy my curiosity on one point first, Mr. Gryce. How came you to know as much as you do about last night's proceedings? You could not have been in the house. Did Mother Jane talk after she got back?" The tip of his cane was up, and he frowned at it. Then the handle took its place, and he gave it a good-natured smile.
