The Duke of Datchet, coming out of the bank, lingered for a moment on the steps. In one hand he carried a canvas bag which seemed well weighted. On his countenance there was an expression which to a casual observer might have suggested that his grace was not completely at his ease. That casual observer happened to come strolling by. It took the form of Ivor Dacre.

Mr. Dacre looked the Duke of Datchet up and down in that languid way he has. He perceived the canvas bag. Then he remarked, possibly intending to be facetious:

"Been robbing the bank? Shall I call a cart?"

Nobody minds what Ivor Dacre says. Besides, he is the duke's own cousin. Perhaps a little removed; still, there it is. So the duke smiled a sickly smile, as if Mr. Dacre's delicate wit had given him a passing touch of indigestion.

Mr. Dacre noticed that the duke looked sallow, so he gave his pretty sense of humor another airing.

"Kitchen boiler burst? When I saw the duchess just now I wondered if it had."

His grace distinctly started. He almost dropped the canvas bag.

"You saw the duchess just now, Ivor! When?"

The duke was evidently moved. Mr. Dacre was stirred to languid curiosity. "I can't say I clocked it. Perhaps half an hour ago; perhaps a little more."

"Half an hour ago! Are you sure? Where did you see her?"

Mr. Dacre wondered. The Duchess of Datchet could scarcely have been eloping in broad daylight. Moreover, she had not yet been married a year. Everyone knew that she and the duke were still as fond of each other as if they were not man and wife. So, although the duke, for some cause or other, was evidently in an odd state of agitation, Mr. Dacre saw no reason why he should not make a clean breast of all he knew.

"She was going like blazes in a hansom cab."

"In a hansom cab? Where?"

"Down Waterloo Place."

"Was she alone?"

Mr. Dacre reflected. He glanced at the duke out of the corners of his eyes. His languid utterance became a positive drawl.

"I rather fancy that she wasn't."

"Who was with her?"

"My dear fellow, if you were to offer me the bank I couldn't tell you."

"Was it a man?"

Mr. Dacre's drawl became still more pronounced.

"I rather fancy that it was."

Mr. Dacre expected something. The duke was so excited. But he by no means expected what actually came.

"Ivor, she's been kidnaped!"

Mr. Dacre did what he had never been known to do before within the memory of man—he dropped his eyeglass.

"Datchet!"

"She has! Some scoundrel has decoyed her away, and trapped her. He's already sent me a lock of her hair, and he tells me that if I don't let him have five hundred pounds in gold by half-past five he'll let me have her little finger."

Mr. Dacre did not know what to make of his grace at all. He was a sober man—it couldn't be that! Mr. Dacre felt really concerned.

"I'll call a cab, old man, and you'd better let me see you home."

Mr. Dacre half raised his stick to hail a passing hansom. The duke caught him by the arm.

"You ass! What do you mean? I am telling you the simple truth. My wife's been kidnaped."

Mr. Dacre's countenance was a thing to be seen—and remembered.

"Oh! I hadn't heard that there was much of that sort of thing about just now. They talk of poodles being kidnaped, but as for duchesses—You'd really better let me call that cab."

"Ivor, do you want me to kick you? Don't you see that to me it's a question of life and death? I've been in there to get the money." His grace motioned toward the bank. "I'm going to take it to the scoundrel who has my darling at his mercy. Let me but have her hand in mine again, and he shall continue to pay for every sovereign with tears of blood until he dies."

"Look here, Datchet, I don't know if you're having a joke with me, or if you're not well—"

The duke stepped impatiently into the roadway.

"Ivor, you're a fool! Can't you tell jest from earnest, health from disease? I'm off! Are you coming with me? It would be as well that I should have a witness."

"Where are you off to?"

"To the other end of the Arcade."

"Who is the gentleman you expect to have the pleasure of meeting there?"

"How should I know?" The duke took a letter from his pocket—it was the letter which had just arrived. "The fellow is to wear a white top hat, and a gardenia in his buttonhole."

"What is it you have there?"

"It's the letter which brought the news—look for yourself and see; but, for God's sake, make haste!" His grace glanced at his watch. "It's already twenty after five."

"And do you mean to say that on the strength of a letter such as this you are going to hand over five hundred pounds to—"

The duke cut Mr. Dacre short.

"What are five hundred pounds to me? Besides, you don't know all. There is another letter. And I have heard from Mabel. But I will tell you all about it later. If you are coming, come!"

Folding up the letter, Mr. Dacre returned it to the duke.

"As you say, what are five hundred pounds to you? It's as well they are not as much to you as they are to me, or I'm afraid—"

"Hang it, Ivor, do prose afterwards!"

The duke hurried across the road. Mr. Dacre hastened after him. As they entered the Arcade they passed a constable. Mr. Dacre touched his companion's arm.

"Don't you think we'd better ask our friend in blue to walk behind us? His neighborhood might be handy."

"Nonsense!" The duke stopped short. "Ivor, this is my affair, not yours. If you are not content to play the part of silent witness, be so good as to leave me."

"My dear Datchet, I'm entirely at your service. I can be every whit as insane as you, I do assure you."

Side by side they moved rapidly down the Burlington Arcade. The duke was obviously in a state of the extremest nervous tension. Mr. Dacre was equally obviously in a state of the most supreme enjoyment. People stared as they rushed past. The duke saw nothing. Mr. Dacre saw everything, and smiled.

When they reached the Piccadilly end of the Arcade the duke pulled up. He looked about him. Mr. Dacre also looked about him.

"I see nothing of your white-hatted and gardenia-buttonholed friend," said Ivor.

The duke referred to his watch.

"It's not yet half-past five. I'm up to time."

Mr. Dacre held his stick in front of him and leaned on it. He indulged himself with a beatific smile.

"It strikes me, my dear Datchet, that you've been the victim of one of the finest things in hoaxes—"

"I hope I haven't kept you waiting."

The voice which interrupted Mr. Dacre came from the rear. While they were looking in front of them some one approached them from behind, apparently coming out of the shop which was at their backs.

The speaker looked a gentleman. He sounded like one, too. Costume, appearance, manner, were beyond reproach—even beyond the criticism of two such keen critics as were these. The glorious attire of a London dandy was surmounted with a beautiful white top hat. In his buttonhole was a magnificent gardenia.

In age the stranger was scarcely more than a boy, and a sunny-faced, handsome boy at that. His cheeks were hairless, his eyes were blue. His smile was not only innocent, it was bland. Never was there a more conspicuous illustration of that repose which stamps the caste of Vere de Vere.

The duke looked at him and glowered. Mr. Dacre looked at him and smiled.

"Who are you?" asked the duke.

"Ah—that is the question!" The newcomer's refined and musical voice breathed the very soul of affability. "I am an individual who is so unfortunate as to be in want of five hundred pounds."

"Are you the scoundrel who sent me that infamous letter?"
