Rosamund looked at the two doctors, her face growing paler and paler. Then her eyes strayed to Michael, who was leaning on the gate; but he continued to lean on it without moving, with his face turned away towards the darkening road.

The criminal specialist who had come with Dr. Warner was a somewhat more urbane and even dapper figure than he had appeared when clutching the railings and craning his neck into the garden. He even looked comparatively young when he took his hat off, having fair hair parted in the middle and carefully curled on each side, and lively movements, especially of the hands. He had a dandified monocle slung round his neck by a broad black ribbon, and a big bow tie, as if a big American moth had alighted on him. His dress and gestures were bright enough for a boy’s; it was only when you looked at the fish-bone face that you beheld something acrid and old. His manners were excellent, though hardly English, and he had two half-conscious tricks by which people who only met him once remembered him. One was a trick of closing his eyes when he wished to be particularly polite; the other was one of lifting his joined thumb and forefinger in the air as if holding a pinch of snuff, when he was hesitating or hovering over a word. But hose who were longer in his company tended to forget these oddities in the stream of his quaint and solemn conversation and really singular views.

“Miss Hunt,” said Dr. Warner, “this is Dr. Cyrus Pym.”

Dr. Cyrus Pym shut his eyes during the introduction, rather as if he were “playing fair” in some child’s game, and gave a prompt little bow, which somehow suddenly revealed him as a citizen of the United States.

“Dr. Cyrus Pym,” continued Warner (Dr. Pym shut his eyes again), “is perhaps the first criminological expert of America. We are very fortunate to be able to consult with him in this extraordinary case–”

“I can’t make head or tail of anything,” said Rosamund. “How can poor Mr. Smith be so dreadful as he is by your account?”

“Or by your telegram,” said Herbert Warner, smiling.

“Oh, you don’t understand,” cried the girl impatiently. “Why, he’s done us all more good than going to church.”

“I think I can explain to the young lady,” said Dr. Cyrus Pym. “This criminal or maniac Smith is a very genius of evil, and has a method of his own, a method of the most daring ingenuity. He is popular wherever he goes, for he invades every house as an uproarious child. People are getting suspicious of all the respectable disguises for a scoundrel; so he always uses the disguise of–what shall I say–the Bohemian, the blameless Bohemian. He always carries people off their feet. People are used to the mask of conventional good conduct. He goes in for eccentric good-nature. You expect a Don Juan to dress up as a solemn and solid Spanish merchant; but you’re not prepared when he dresses up as Don Quixote. You expect a humbug to behave like Sir Charles Grandison; because (with all respect, Miss Hunt, for the deep, tear-moving tenderness of Samuel Richardson) Sir Charles Grandison so often behaved like a humbug. But no real red-blooded citizen is quite ready for a humbug that models himself not on Sir Charles Grandison but on Sir Roger de Coverly. Setting up to be a good man a little cracked is a new criminal incognito, Miss Hunt. It’s been a great notion, and uncommonly successful; but its success just makes it mighty cruel. I can forgive Dick Turpin if he impersonates Dr. Busby; I can’t forgive him when he impersonates Dr. Johnson. The saint with a tile loose is a bit too sacred, I guess, to be parodied.”

“But how do you know,” cried Rosamund desperately, “that Mr. Smith is a known criminal?”

“I collated all the documents,” said the American, “when my friend Warner knocked me up on receipt of your cable. It is my professional affair to know these facts, Miss Hunt; and there’s no more doubt about them than about the Bradshaw down at the depot. This man has hitherto escaped the law, through his admirable affectations of infancy or insanity. But I myself, as a specialist, have privately authenticated notes of some eighteen or twenty crimes attempted or achieved in this manner. He comes to houses as he has to this, and gets a grand popularity. He makes things go. They do go; when he’s gone the things are gone. Gone, Miss Hunt, gone, a man’s life or a man’s spoons, or more often a woman. I assure you I have all the memoranda.”

“I have seen them,” said Warner solidly, “I can assure you that all this is correct.”

“The most unmanly aspect, according to my feelings,” went on the American doctor, “is this perpetual deception of innocent women by a wild simulation of innocence. From almost every house where this great imaginative devil has been, he has taken some poor girl away with him; some say he’s got a hypnotic eye with his other queer features, and that they go like automata. What’s become of all those poor girls nobody knows. Murdered, I dare say; for we’ve lots of instances, besides this one, of his turning his hand to murder, though none ever brought him under the law. Anyhow, our most modern methods of research can’t find any trace of the wretched women. It’s when I think of them that I am really moved, Miss Hunt. And I’ve really nothing else to say just now except what Dr. Warner has said.”

“Quite so,” said Warner, with a smile that seemed moulded in marble–“that we all have to thank you very much for that telegram.”

The little Yankee scientist had been speaking with such evident sincerity that one forgot the tricks of his voice and manner– the falling eyelids, the rising intonation, and the poised finger and thumb–which were at other times a little comic. It was not so much that he was cleverer than Warner; perhaps he was not so clever, though he was more celebrated. But he had what Warner never had, a fresh and unaffected seriousness– the great American virtue of simplicity. Rosamund knitted her brows and looked gloomily toward the darkening house that contained the dark prodigy.

Broad daylight still endured; but it had already changed from gold to silver, and was changing from silver to gray. The long plumy shadows of the one or two trees in the garden faded more and more upon a dead background of dusk. In the sharpest and deepest shadow, which was the entrance to the house by the big French windows, Rosamund could watch a hurried consultation between Inglewood (who was still left in charge of the mysterious captive) and Diana, who had moved to his assistance from without. After a few minutes and gestures they went inside, shutting the glass doors upon the garden; and the garden seemed to grow grayer still.

The American gentleman named Pym seemed to be turning and on the move in the same direction; but before he started he spoke to Rosamund with a flash of that guileless tact which redeemed much of his childish vanity, and with something of that spontaneous poetry which made it difficult, pedantic as he was, to call him a pedant.

“I’m vurry sorry, Miss Hunt,” he said; “but Dr. Warner and I, as two quali-FIED practitioners, had better take Mr. Smith away in that cab, and the less said about it the better. Don’t you agitate yourself, Miss Hunt. You’ve just got to think that we’re taking away a monstrosity, something that oughtn’t to be at all–something like one of those gods in your Britannic Museum, all wings, and beards, and legs, and eyes, and no shape. That’s what Smith is, and you shall soon be quit of him.”

He had already taken a step towards the house, and Warner was about to follow him, when the glass doors were opened again and Diana Duke came out with more than her usual quickness across the lawn. Her face was aquiver with worry and excitement, and her dark earnest eyes fixed only on the other girl.
