"Finish what you have to say," said William.

"I confess I knew the prisoner at the Hague."

"Happy prisoner!" said William, smiling.

At this moment the officer who had been sent for Boxtel returned, and announced to the Prince that the person whom he had been to fetch was following on his heels with his tulip.

Boxtel's return was scarcely announced, when he entered in person the drawing-room of Mynheer van Systens, followed by two men, who carried in a box their precious burden and deposited it on a table.

The Prince, on being informed, left the cabinet, passed into the drawing-room, admired the flower, and silently resumed his seat in the dark corner, where he had himself placed his chair.

Rosa, trembling, pale and terrified, expected to be invited in her turn to see the tulip.

She now heard the voice of Boxtel.

"It is he!" she exclaimed.

The Prince made her a sign to go and look through the open door into the drawing-room.

"It is my tulip," cried Rosa, "I recognise it. Oh, my poor Cornelius!"

And saying this she burst into tears.

The Prince Prince rose from his seat, went to the door, where he stood for some time with the full light falling upon his figure.

As Rosa's eyes now rested upon him, she felt more than ever convinced that this was not the first time she had seen the stranger.

"Master Boxtel," said the Prince, "come in here, if you please."

Boxtel eagerly approached, and, finding himself face to face with William of Orange, started back.

"His Highness!" he called out.

"His Highness!" Rosa repeated in dismay.

Hearing this exclamation on his left, Boxtel turned round, and perceived Rosa.

At this sight the whole frame of the thief shook as if under the influence of a galvanic shock.

"Ah!" muttered the Prince to himself, "he is confused."

But Boxtel, making a violent effort to control his feelings, was already himself again.

"Master Boxtel," said William, "you seem to have discovered the secret of growing the black tulip?"

"Yes, your Highness," answered Boxtel, in a voice which still betrayed some confusion.

It is true his agitation might have been attributable to the emotion which the man must have felt on suddenly recognising recognising the Prince.

"But," continued the Stadtholder, "here is a young damsel who also pretends to have found it."

Boxtel, with a disdainful smile, shrugged his shoulders.

William watched all his movements with evident interest and curiosity.

"Then you don't know this young girl?" said the Prince.

"No, your Highness!"

"And you, child, do you know Master Boxtel?"

"No, I don't know Master Boxtel, but I know Master Jacob."

"What do you mean?"

"I mean to say that at Loewestein the man who here calls himself Isaac Boxtel went by the name of Master Jacob."

"What do you say to that, Master Boxtel?"

"I say that this damsel lies, your Highness."

"You deny, therefore, having ever been at Loewestein?"

Boxtel hesitated; the fixed and searching glance of the proud eye of the Prince prevented him from lying.

We waited in silence for a minute — one of those minutes which one can never forget. Then the door opened and the man stepped in. In an instant Holmes clapped a pistol to his head, and Martin slipped the handcuffs over his wrists. It was all done so swiftly and deftly that the fellow was helpless before he knew that he was attacked. He glared from one to the other of us with a pair of blazing black eyes. Then he burst into a bitter laugh.

“Well, gentlemen, you have the drop on me this time. I seem to have knocked up against something hard. But I came here in answer to a letter from Mrs. Hilton Cubitt. Don’t tell me that she is in this? Don’t tell me that she helped to set a trap for me?”

“Mrs. Hilton Cubitt was seriously injured, and is at death’s door.”

The man gave a hoarse cry of grief, which rang through the house.

“You’re crazy!” he cried, fiercely. “It was he that was hurt, not she. Who would have hurt little Elsie? I may have threatened her — God forgive me! — but I would not have touched a hair of her pretty head. Take it back — you! Say that she is not hurt!”

“She was found, badly wounded, by the side of her dead husband.”

He sank with a deep groan on to the settee, and buried his face in his manacled hands. For five minutes he was silent. Then he raised his face once more, and spoke with the cold composure of despair.

“I have nothing to hide from you, gentlemen,” said he. “If I shot the man he had his shot at me, and there’s no murder in that. But if you think I could have hurt that woman, then you don’t know either me or her. I tell you, there was never a man in this world loved a woman more than I loved her. I had a right to her. She was pledged to me years ago. Who was this Englishman that he should come between us? I tell you that I had the first right to her, and that I was only claiming my own.”

“She broke away from your influence when she found the man that you are,” said Holmes, sternly. “She fled from America to avoid you, and she married an honourable gentleman in England. You dogged her and followed her and made her life a misery to her, in order to induce her to abandon the husband whom she loved and respected in order to fly with you, whom she feared and hated. You have ended by bringing about the death of a noble man and driving his wife to suicide. That is your record in this business, Mr. Abe Slaney, and you will answer for it to the law.

“If Elsie dies, I care nothing what becomes of me,” said the American. He opened one of his hands, and looked at a note crumpled up in his palm. “See here, mister,” he cried, with a gleam of suspicion in his eyes, “you’re not trying to scare me over this, are you? If the lady is hurt as bad as you say, who was it that wrote this note?” He tossed it forward on to the table.

“I wrote it, to bring you here.”

“You wrote it? There was no one on earth outside the Joint who knew the secret of the dancing men. How came you to write it?”
