"What things?"
"Well, in the first place, that he is conscientious. He doesn't waste time. He writes with one hand while he takes his tea with the other; which of course is very clever of him. He's marvellously ambidexterous so long as he doesn't know you're looking at him. Unfortunately, my eye arrested him in the double act. Lucy, my eye must have some horrible malignant power, for it instantly gave him St. Vitus's dance. Have you ever noticed anything peculiar about my eye?"
"What a shame."
"Yes. I'm afraid he'll have to do a little re-copying."
"Oh, Kitty, why couldn't you leave the poor thing in peace?"
"There wasn't any peace to leave him in. Really, you'd have thought that taking afternoon tea was an offence within the meaning of the Act. He couldn't have been more excited if I'd caught him in his bath. Mr. Rickman suffers from excess of modesty."
"Mr. Rickman could hardly say the same of you. You might have had the decency to go away."
"There wouldn't have been any decency in going away. Flight would have argued that I shared the theory of his guilt. I stayed where I was for two seconds just to reassure him; then I went away—to the other end of the room."
"You should have gone away altogether."
"Why? The library is big enough for two. It's so big that you could take a bath or do a murder at one end without anybody being aware of it at the other. I went away; I wandered round the bookcases; I even hummed a tune, not so much to show that I was at my ease as to set him at his."
