Whenever in the future I wish to hear from Dawson of his exploits I shall not seek him at his own house. He is an artist who is highly sensitive to atmosphere. In Acacia Villas the police officer fades to shadowy insignificance, even in his own mind. Then, he is a husband, a father, and a mighty preacher. He will talk of his disguises, and in general terms of his work, but there is no fiery enthusiasm for manhunting when Dawson gets home to Tooting. I shall seek him at the Yard, or upon the hot trail; then and then only shall I get from him the full flavour of his genius for detection. Dawson, away from home, is so vain as to be unconscious of his vanity; Dawson at home is quite extraordinarily modest. He defers always to the opinion of Emma, and she, gently, kindly, but with an air of infinite superiority, keeps his wandering steps firmly in the path of truth. He is, I am told, a most kindling preacher, but it is Emma who inspires his sermons. Once only during my visit did I see a flash of the old Dawson, the Dawson of the _Malplaquet_, and of the War Committee, and that was just before I left. We were in the parlour smoking, and I was getting rather bored. Conjugal virtue, domestic content and happiness, are beautiful to look upon for a while, but I confess that in a remorseless continuous film ("featuring" Dawson and Emma) I find them boresome. There is little humour about Dawson and none at all about his dear Emma. I would gladly exchange fifty virtuous Emmas for one naughty Madame Gilbert. We had been talking idly of our sport together and of his different incarnations. Suddenly he sprang from his chair and his pale face lighted up. "Now that I have you here, Mr. Copplestone, I shall not let you go until you tell me by what trick you can always see through my disguises. Would you know me now as Dawson?" "Of course," said I. "There is no difficulty. If you painted your face black and your hair vermilion, I should still know you at once." "You have promised to tell me the secret. Tell me now." I considered whether I should tell. It was amusing to have some hold over him, but was it quite fair to Dawson to keep him in ignorance of those marks of ear by which I could always be certain of his identity. He had been useful to me, and I had made free with his personality. Yes, I would tell him, and in a few sentences I told. He gripped his ears with both hands; he felt those lobes so firmly secured to his cheekbones, and those blobs of flesh which remained to him of his wolfish ancestors. He fingered them carefully while he thought. At last he made up his mind. "It is the Sabbath," said he, "but when I am on duty I work ever upon the Sabbath day. It is now my duty to--" He reached for the telephone book, took off the receiver, and called for a number. "What are you doing?" I asked, though I ought to have known. "I am making an appointment with a surgeon," said Dawson. THE END
