So his Grace explained:
"That is the half of a sixpence which I gave to the Duchess when I asked her to be my wife. You see it is pierced. I pierced that hole in it myself. As the Duchess says in this letter, and as I have reason to know, she has worn this broken sixpence from that hour to this. If this letter is not hers, how came this token in the envelope? How came any one to know, even, that she carried it?"
Mr. Knowles was silent. He still yielded to his constitutional disrelish to commit himself. At last he asked:
"What is it that your Grace proposes to do?"
The Duke spoke with a bitterness which almost suggested a personal animosity towards the inoffensive Mr. Knowles.
"I propose, with your permission, to release the Duchess from the custody of my estimable correspondent. I propose--always with your permission--to comply with his modest request, and to take him his five hundred pounds in gold." He paused, then continued in a tone which, coming from him, meant volumes: "Afterwards, I propose to cry quits with the concoctor of this pretty little hoax, even if it costs me every penny I possess. He shall pay more for that five hundred pounds than he supposes."
CHAPTER II.
SOUGHT.
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 humour 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. Every one 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 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 kidnapped!"
Mr. Dacre did what he had never been known to do before within the memory of man--he dropped his eye-glass.
"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 kidnapped."
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 kidnapped, 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 towards 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 button hole."
"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 neighbourhood 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
