five hundred pounds, you--you----"

As the Duke paused, as if at a loss for language which was strong enough to convey his meaning, the stranger laughed.

"Let us take the adjectives for granted. Besides, it is only boys who call each other names--men do things. If you give me the five hundred sovereigns, which you have in that bag, at once--in five minutes it will be too late--I will promise--I will not swear; if you do not credit my simple promise, you will not believe my solemn affirmation--I will promise that, possibly within an hour, certainly within an hour and a half, the Duchess of Datchet shall return to you absolutely uninjured--except, of course, as you are already aware, with regard to a few of the hairs of her head. I will promise this on the understanding that you do not yourself attempt to see where I go, and that you will allow no one else to do so." This with a glance at Ivor Dacre. "I shall know at once if I am followed. If you entertain any such intentions, you had better, on all accounts, remain in possession of your five hundred pounds."

The Duke eyed him very grimly:

"I entertain no such intentions--until the Duchess returns."

Again the stranger indulged in that musical little laugh of his:

"Ah, until the Duchess returns! Of course, then the bargain's at an end. When you are once more in the enjoyment of her Grace's society, you will be at liberty to set all the dogs in Europe at my heels. I assure you I fully expect that you will do so--why not?" The Duke raised the canvas bag. "My dear Duke, ten thousand thanks! You shall see her Grace at Datchet House, 'pon my honour. Probably within the hour."

"Well," commented Ivor Dacre, when the stranger had vanished, with the bag, into Piccadilly, and as the Duke and himself moved towards Burlington Gardens, "if a gentleman is to be robbed, it is as well that he should have another gentleman to rob him."

CHAPTER III.

AND FOUND.

Mr. Dacre eyed his companion covertly as they progressed. His Grace of Datchet appeared to have some fresh cause for uneasiness. All at once he gave it utterance, in a tone of voice which was extremely sombre:

"Ivor, do you think that scoundrel will dare to play me false?"

"I think," murmured Mr. Dacre, "that he has dared to play you pretty false already."

"I don't mean that. But I mean how am I to know, now that he has his money, that he will still not keep Mabel in his clutches?"

There came an echo from Mr. Dacre:

"Just so--how are you to know?"

"I believe that something of this sort has been done in the United States."

"I thought that there they were content to kidnap them after they were dead. I was not aware that they had, as yet, got quite so far as the living."

"I believe that I have heard of something just like this."

"Possibly; they are giants over there."

"And in that case the scoundrels, when their demands were met, refused to keep to the letter of their bargain, and asked for more."

The Duke stood still. He clenched his fists, and swore:

"Ivor, if that ---- villain doesn't keep his word, and Mabel isn't home within the hour, by ---- I shall go mad!"

"My dear Datchet"--Mr. Dacre loved strong language as little as he loved a scene--"let us trust to time and, a little, to your white-hatted and gardenia-button-holed friend's word of honour. You should have thought of possible eventualities before you showed your confidence--really. Suppose, instead of going mad, we first of all go home?"

A hansom stood waiting for a fare at the end of the Arcade. Mr. Dacre had handed the Duke into it before his Grace had quite realised that the vehicle was there.

"Tell the fellow to drive faster." That was what the Duke said when the cab had started.

"My dear Datchet, the man's already driving his geegee off its legs. If a bobby catches sight of him he'll take his number."

A moment later, a murmur from the Duke:

"I don't know if you're aware that the Prince is coming to dinner?"

"I am perfectly aware of it."

"You take it uncommonly coolly. How easy it is to bear our brother's burdens! Ivor, if Mabel doesn't turn up I shall feel like murder."

"I sympathise with you, Datchet, with all my heart, though, I may observe, parenthetically, that I very far from realise the situation even yet. Take my advice. If the Duchess does not show quite so soon as we both of us desire, don't make a scene; just let me see what I can do."

Judging from the expression of his countenance, the Duke was conscious of no overwhelming desire to witness an exhibition of Mr. Dacre's prowess.

When the cab reached Datchet House his Grace dashed up the steps three at a time. The door flew open.

"Has the Duchess returned?"

"Hereward!"

A voice floated downwards from above. Some one came running down the stairs. It was her Grace of Datchet.

"Mabel!"

She actually rushed into the Duke's extended arms. And he kissed her, and she kissed him--before the servants.

"So you're not quite dead?" she cried.

"I am almost," he said.

She drew herself a little away from him.

"Hereward, were you seriously hurt?"

"Do you suppose that I could have been otherwise than seriously hurt?"

"My darling! Was it a Pickford's van?"

The Duke stared:

"A Pickford's van? I don't understand. But come in here. Come along, Ivor. Mabel, you don't see Ivor."

"How do you do, Mr. Dacre?"

Then the trio withdrew into a little ante-room; it was really time. Even then the pair conducted themselves as if Mr. Dacre had been nothing and no one. The Duke took the lady's two hands in his. He eyed her fondly.

"So you are uninjured, with the exception of that lock of hair. Where did the villain take it from?"

The lady looked a little puzzled:

"What lock of hair?"

From an envelope which he took from his pocket the Duke produced a shining tress. It was the lock of hair which had arrived in the first communication. "I will have it framed."

"You will have what framed?" The Duchess glanced at what the Duke was so tenderly caressing, almost, as it seemed, a little dubiously, "Whatever is it you have there?"

"It is the lock of hair which that scoundrel sent me." Something in the lady's face caused him to ask a question: "Didn't he tell you he had sent it me?"

"Hereward!"

"Did the brute tell you that he meant to cut off your little finger?"

A very curious look came into the lady's face. She glanced at the Duke as if she, all at once, were half afraid of him. She cast at Mr. Dacre what really seemed to be a look of enquiry. Her voice was tremulously anxious:

"Hereward, did--did the accident affect you mentally?"

"How could it not have affected me mentally? Do you think that my mental organization is of steel?"

"But you look so well?"

"Of course I look well, now that I have you back again. Tell me, darling, did that hound actually threaten you with cutting off your arm? If he did, I shall feel half
