“I confess with the greatest sympathy and reverence that I don't quite see it,” I said. “Is it so very extraordinary or complicated that a dreamy somnambulant old invalid who has always walked on the borders of the inconceivable should go mad under the shock of great joy? Is it so very extraordinary that a man with a head like a turnip and a soul like a spider's web should not find his strength equal to a confounding change of fortunes? Is it, in short, so very extraordinary that James Chadd should lose his wits from excitement?” “It would not be extraordinary in the least,” answered Basil, with placidity. “It would not be extraordinary in the least,” he repeated, “if the professor had gone mad. That was not the extraordinary circumstance to which I referred.” “What,” I asked, stamping my foot, “was the extraordinary thing?” “The extraordinary thing,” said Basil, ringing the bell, “is that he has not gone mad from excitement.” The tall and angular figure of the eldest Miss Chadd blocked the doorway as the door opened. Two other Miss Chadds seemed in the same way to be blocking the narrow passage and the little parlour. There was a general sense of their keeping something from view. They seemed like three black-clad ladies in some strange play of Maeterlinck, veiling the catastrophe from the audience in the manner of the Greek chorus. “Sit down, won't you?” said one of them, in a voice that was somewhat rigid with pain. “I think you had better be told first what has happened.” Then, with her bleak face looking unmeaningly out of the window, she continued, in an even and mechanical voice: “I had better state everything that occurred just as it occurred. This morning I was clearing away the breakfast things, my sisters were both somewhat unwell, and had not come down. My brother had just gone out of the room, I believe, to fetch a book. He came back again, however, without it, and stood for some time staring at the empty grate. I said, 'Were you looking for anything I could get?' He did not answer, but this constantly happens, as he is often very abstracted. I repeated my question, and still he did not answer. Sometimes he is so wrapped up in his studies that nothing but a touch on the shoulder would make him aware of one's presence, so I came round the table towards him. I really do not know how to describe the sensation which I then had. It seems simply silly, but at the moment it seemed something enormous, upsetting one's brain. The fact is, James was standing on one leg.” Grant smiled slowly and rubbed his hands with a kind of care. “Standing on one leg?” I repeated.
