In his wake followed two officers, one of the navy, and the other of the cavalry.

Van Systens, having found his way through the frightened domestics, began to bow, almost to prostrate himself before his visitor, who had been the cause of all this stir.

"Monseigneur," he called out, "Monseigneur! What distinguished honour is your Highness bestowing for ever on my humble house by your visit?"

"Dear Mynheer van Systens," said William of Orange, with a serenity which, with him, took the place of a smile, "I am a true Hollander, I am fond of the water, of beer, and of flowers, sometimes even of that cheese the flavour of which seems so grateful to the French; the flower which I prefer to all others is, of course, the tulip. I heard at Leyden that the city of Haarlem at last possessed the black tulip; and, after having satisfied myself of the truth of news which seemed so incredible, I have come to know all about it from from the President of the Horticultural Society."

"Oh, Monseigneur, Monseigneur!" said Van Systens, "what glory to the society if its endeavours are pleasing to your Highness!"

"Have you got the flower here?" said the Prince, who, very likely, already regretted having made such a long speech.

"I am sorry to say we have not."

"And where is it?"

"With its owner."

"Who is he?"

"An honest tulip-grower of Dort."

"His name?"

"Boxtel."

"His quarters?"

"At the White Swan; I shall send for him, and if in the meanwhile your Highness will do me the honour of stepping into my drawing-room, he will be sure -- knowing that your Highness is here -- to lose no time in bringing his tulip."

"Very well, send for him."

"Yes, your Highness, but ----

"What is it?"

"Oh, nothing of any consequence, Monseigneur."

"Everything is of consequence, Mynheer van Systens."

"Well, then, Monseigneur, if it must be said, a little difficulty has presented itself."

"What difficulty?"

"This tulip has already been claimed by usurpers. It's true that it is worth a hundred thousand guilders."

"Indeed!"

"Yes, Monseigneur, by usurpers, by by forgers."

"This is a crime, Mynheer van Systens."

"So it is, your Highness."

"And have you any proofs of their guilt? '

"No, Monseigneur, the guilty woman ---- "

"The guilty woman, Sir?"

"I ought to say, the woman who claims the tulip, Monseigneur, is here in the room close by."

"And what do you think of her?"

"I think, Monseigneur, that the bait of a hundred thousand guilders may have tempted her."

"And so she claims the tulip?"

"Yes Monseigneur."

"And what proof does she offer?"

"I was just going to question her when your Highness came in."

"Question her, Mynheer van Systens, question her. I am the first magistrate of the country; I will hear the case and administer justice."

"I have found my King Solomon," said Van Systens, bowing, and showing the way to the Prince.

His Highness was just going to walk ahead, but, suddenly recollecting himself he said --

"Go before me, and call me plain Mynheer."

The two then entered the cabinet.

My mind filled with admiration for this extraordinary man.

“You have solved it!” I cried.

“Hardly that, Watson. There are some points which are as dark as ever. But we have so much that it will be our own fault if we cannot get the rest. We will go straight to Whitehall Terrace and bring the matter to a head.”

When we arrived at the residence of the European Secretary it was for Lady Hilda Trelawney Hope that Sherlock Holmes inquired. We were shown into the morning-room.

“Mr. Holmes!” said the lady, and her face was pink with her indignation. “This is surely most unfair and ungenerous upon your part. I desired, as I have explained, to keep my visit to you a secret, lest my husband should think that I was intruding into his affairs. And yet you compromise me by coming here and so showing that there are business relations between us.”

“Unfortunately, madam, I had no possible alternative. I have been commissioned to recover this immensely important paper. I must therefore ask you, madam, to be kind enough to place it in my hands.”

The lady sprang to her feet, with the colour all dashed in an instant from her beautiful face. Her eyes glazed — she tottered — I thought that she would faint. Then with a grand effort she rallied from the shock, and a supreme astonishment and indignation chased every other expression from her features.

“You — you insult me, Mr. Holmes.”

“Come, come, madam, it is useless. Give up the letter.”

She darted to the bell.

“The butler shall show you out.”

“Do not ring, Lady Hilda. If you do, then all my earnest efforts to avoid a scandal will be frustrated. Give up the letter and all will be set right. If you will work with me I can arrange everything. If you work against me I must expose you.”

She stood grandly defiant, a queenly figure, her eyes fixed upon his as if she would read his very soul. Her hand was on the bell, but she had forborne to ring it.

“You are trying to frighten me. It is not a very manly thing, Mr. Holmes, to come here and browbeat a woman. You say that you know something. What is it that you know?”

“Pray sit down, madam. You will hurt yourself there if you fall. I will not speak until you sit down. Thank you.”

“I give you five minutes, Mr. Holmes.”

“One is enough, Lady Hilda. I know of your visit to Eduardo Lucas, of your giving him this document, of your ingenious return to the room last night, and of the manner in which you took the letter from the hiding-place under the carpet.”

She stared at him with an ashen face and gulped twice before she could speak.

“You are mad, Mr. Holmes — you are mad!” she cried, at last.

He drew a small piece of cardboard from his pocket. It was the face of a woman cut out of a portrait.

“I have carried this because I thought it might be useful,” said he. “The policeman has recognized it.”
