He was a spare little man, resembling the stem of a flower, his head forming its chalice, and his two limp arms representing the double leaf of the tulip; the resemblance was rendered complete by his waddling gait which made him even more like that flower when it bends under a breeze.

"Well, miss," he said, "you are coming, I am told, about the affair of the black tulip."

To the President of the Horticultural Society the Tulipa nigra was a first-rate power, which, in its character as queen of the tulips, might send ambassadors.

"Yes, sir," answered Rosa; "I come at least to speak of it."

"Is it doing well, then?" asked Van Systens, with a smile of tender veneration.

"Alas! sir, I don't know," said Rosa.

"How is that? could any misfortune have happened to it?"

"A very great one, sir; yet not to it, but to me."

"What?"

"It has been stolen from me."

"Stolen! the black tulip?"

"Yes, sir."

"Do you know the thief?"

"I have my suspicions, but I must not yet accuse any one."

"But the matter may very easily be ascertained."

"How is that?"

"As it has been stolen from you, the thief cannot be far off."

"Why not?"

"Because I have seen the black tulip only two hours ago."

"You have seen the black tulip!" cried Rosa, rushing up to Mynheer van Systens.

"As I see see you, miss."

"But where?"

"Well, with your master, of course."

"With my master?"

"Yes, are you not in the service of Master Isaac Boxtel?"

"I?"

"Yes, you."

"But for whom do you take me, sir?"

"And for whom do you take me?"

"I hope, sir, I take you for what you are, -- that is to say, for the honorable Mynheer van Systens, Burgomaster of Haarlem, and President of the Horticultural Society."

"And what is it you told me just now?"

"I told you, sir, that my tulip has been stolen."

"Then your tulip is that of Mynheer Boxtel. Well, my child, you express yourself very badly. The tulip has been stolen, not from you, but from Mynheer Boxtel."

"I repeat to you, sir, that I do not know who this Mynheer Boxtel is, and that I have now heard his name pronounced for the first time."

"You do not know who Mynheer Boxtel is, and you also had a black tulip?"

"But is there any other besides mine?" asked Rosa, trembling.

"Yes, -- that of Mynheer Boxtel."

"How is it?"

"Black, of course."

"Without speck?"

"Without a single speck, or even point."

"And you have this tulip, -- you have it deposited here?"

"No, but it will be, as it has to be exhibited before the committee previous to the prize being awarded."

"Oh, sir!" cried Rosa, "this Boxtel -- this Isaac Boxtel -- who calls himself the owner of the black tulip ---- "

"And who is its owner?"

"Is he not a very thin man?"

"Bald?"

"Yes."

"With sunken eyes?"

"I think he has."

"Restless, stooping, and bowlegged?"

"In truth, you draw Master Boxtel's portrait feature by feature."

"And the tulip, sir? Is it not in a pot of white and blue earthenware, with yellowish flowers in a basket on three sides?"

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?”
