We had finished breakfast the next morning—the Saturday of Dawson's gamble—and were sitting on Cary's big fireguard talking of every subject, except the one which had kept us awake at night, when a servant entered and announced that a soldier was at the door with a message from Mr. Dawson. "Show him in," almost shouted Cary, and I jumped to my feet, stirred for once into a visible display of eagerness.

A Marine came in, dressed in the smart blue sea kit that I love; upon his head the low flat cap of his Corps. He gave us a full swinging salute, and jumped to attention with a click of his heels. He looked about thirty-five, and wore a neatly trimmed dark moustache. His hair, also very dark, was cropped close to his head. Standing there with his hands upon the red seams of his trousers, his chest well filled out, and his face weather tanned, he looked a proper figure of a sea-going soldier. "Mr. Cary, sir," he said, in a flat, monotonous orderly's voice, "Major Boyle's compliments, and could you and your friend come down to the Police Station to meet him and Chief Inspector Dawson. I have a taxi-cab at the door, sir."

"Certainly," cried Cary; "in two minutes we shall be ready."

"Oh, no, we shan't," I remarked calmly, for I had moved to a position of tactical advantage on the Marine's port beam. "We will have the story here, if you don't mind, Dawson."

He stamped pettishly on the floor, whipped off his cap, and spun it across the room. "Confound you, Mr. Copplestone!" he growled. "How the—how the—do you do it?" He could not think of an expletive mild enough for Mrs. Cary's ears. "There's something about me that I can't hide. What is it? If you don't tell, I will get you on the Regulation compelling all British subjects to answer questions addressed to them by a competent naval or military authority."

"You don't happen to be either, Dawson," said I unkindly. "And, beside, there was never yet a law made which could compel a man to speak or a woman to hold her tongue. Some day perhaps, if you are good, I will show you how the trick is done. But not yet. I want to have something to bargain with when you cast me into jail. Out with the story; we are impatient. If I mistake not, you come to us Dawson triumphant. You haven't the air of a broken man."

"I have been successful," he answered gravely, "but I am a long, long way from feeling triumphant. No, thank you, Mrs. Cary, I have had my breakfast, but if I might trouble you for a cup of coffee? Many thanks."

Dawson sat down, and Cary moved about inspecting him from every angle. "No," declared he at last, "I cannot see the smallest resemblance, not the smallest. You were thin; now you are distinctly plump. Your hair was nearly white. Your cheeks had fallen in as if your back teeth were missing. Your lower lip stuck out." Dawson smiled, highly gratified. "I took in all my people at the office this morning," he said. "They all thought, and think still, that I was a messenger from the Malplaquet, which, by the way, is well down the river safe and sound. Just wait a minute." He walked into a corner of the room, moved his hands quickly between his side pockets and his face, and then returned. Except for the dark hair and moustache and the brown skin, he had become the Dawson of the Thursday afternoon. "It is as simple for me to change," said the artist, with a nasty look in my direction, "as it seems to be for Mr. Copplestone here to spot me. It will take a day or two to get the dye out of my hair and the tan off my skin. I am going to have a sharp touch of influenza, which is a useful disease when one wants to lie in. Since Sunday I have only been twice to bed."

We filled him up with coffee and flattery—as one fills a motor car with petrol and oil—but asked him no questions until we were safely in Cary's study and Mrs. Cary had gone about her household duties. "Your good lady," remarked Dawson to Cary, "is as little curious as any woman I have met, and we will leave her at that if you don't mind. The best thing about our women is that they don't care tuppence about naval and military details. If they did, and once started prying with that keen scent and indomitable persistence of theirs, we might as well chuck up. Even my own bright team of charmers never know and never ask the meaning of the information that they ferret out for me. Their curiosity is all personal—about men and women, never about things. Women—"

I cut Dawson short. He tended to become tedious.
