"It is sometimes injudicious to state all that one knows." "Still more so all that one does not know. But I have no desire to press you," the doctor said, lightly. "This is wonderful wine. Where did you get it?" "At the _Cercle Blanc_ sale," Valentine answered quickly. It seemed that he was slightly irritated. He frowned and cast a glance that was almost threatening upon the doctor. "Would you assume weakness in every strong man who refuses to take off his coat, roll up his shirt sleeve and display the muscle of his arm?" he said, harshly. "The case is not analogous. That muscle exists in the world is a proved fact. When I was at Eton, I was knocked down by a boy stronger than I was. Since then I acknowledge the power of muscle." "And have you never been knocked down mentally?" "Not in the way you suggest." Valentine shifted in his seat. It did not escape the doctor that he had the air of a man longing to either say or do something startling, but apparently held back by tugging considerations of prudence or of expediency. "Some day you may be," he said at last, obviously conquered by this prompting prudence. "When I am, the 'Christian scientist' who once declared to me that she cured a sprained ankle by walking on it many miles a day, and thinking it was well while she walked, shall receive my respectful apologies," the doctor answered, laughing. Valentine handed the lady of the feathers some strawberries. On her nervous refusal of them he exclaimed: "I see you have finished your wine, doctor. No more? Really? Nor you, Julian?" Julian made no reply. He simply pushed his glass a little away from him. "Then shall we accompany Miss Bright into the tentroom? I thought we would have coffee there. You have never seen the tentroom," he added to Cuckoo, getting up from his seat as he spoke. "I usually sit in it when I am alone or with Julian. You will not mind our cigarettes, I know." He led the way down the scented corridor, scented with the thin, gently bright scent of violets. "The tentroom has a history," he continued to Cuckoo, opening a door on the left. "It was once the scene of an--an absurd experiment. Eh, doctor?"
