“You are off?”

“Yes, I will while away the morning at Godolphin Street with our friends of the regular establishment. With Eduardo Lucas lies the solution of our problem, though I must admit that I have not an inkling as to what form it may take. It is a capital mistake to theorize in advance of the facts. Do you stay on guard, my good Watson, and receive any fresh visitors. I’ll join you at lunch if I am able.”

All that day and the next and the next Holmes was in a mood which his friends would call taciturn, and others morose. He ran out and ran in, smoked smoked incessantly, played snatches on his violin, sank into reveries, devoured sandwiches at irregular hours, and hardly answered the casual questions which I put to him. It was evident to me that things were not going well with him or his quest. He would say nothing of the case, and it was from the papers that I learned the particulars of the inquest, and the arrest with the subsequent release of John Mitton, the valet of the deceased. The coroner’s jury brought in the obvious Wilful Murder, but the parties remained as unknown as ever. No motive was suggested. The room was full of articles of value, but but none had been taken. The dead man’s papers had not been tampered with. They were carefully examined, and showed that he was a keen student of international politics, an indefatigable gossip, a remarkable linguist, and an untiring letter writer. He had been on intimate terms with the leading politicians of several countries. But nothing sensational was discovered among the documents which filled his drawers. As to his relations with women, they appeared to have been promiscuous but superficial. He had many acquaintances among them, but few friends, and no one whom he loved. His habits were regular, his conduct inoffensive. His death was an absolute mystery and and likely to remain so.

As to the arrest of John Mitton, the valet, it was a council of despair as an alternative to absolute inaction. But no case could be sustained against him. He had visited friends in Hammersmith that night. The alibi was complete. It is true that he started home at an hour which should have brought him to Westminster before the time when the crime was discovered, but his own explanation that he had walked part of the way seemed probable enough in view of the fineness of the night. He had actually arrived at twelve o’clock, and appeared to be overwhelmed by the unexpected tragedy. tragedy He had always been on good terms with his master. Several of the dead man’s possessions — notably a small case of razors — had been found in the valet’s boxes, but he explained that they had been presents from the deceased, and the housekeeper was able to corroborate the story. Mitton had been in Lucas’s employment for three years. It was noticeable that Lucas did not take Mitton on the Continent with him. Sometimes he visited Paris for three months on end, but Mitton was left in charge of the Godolphin Street house. As to the housekeeper, she had heard nothing on the night of the the crime. If her master had a visitor he had himself admitted him.

"Oh, my God, my God! what infamous falsehoods!" said Rosa, bursting into tears, and throwing herself at the feet of the Stadtholder, who, although thinking her guilty, felt pity for her dreadful agony.

"You have done very wrong, my child," he said, "and your lover shall be punished for having thus badly advised you. For you are so young, and have such an honest look, that I am inclined to believe the mischief to have been his doing, and not yours."

"Monseigneur! Monseigneur!" cried Rosa, "Cornelius is not guilty."

William started.

"Not guilty of having advised you? that's what you you want to say, is it not?"

"What I wish to say, your Highness, is that Cornelius is as little guilty of the second crime imputed to him as he was of the first."

"Of the first? And do you know what was his first crime? Do you know of what he was accused and convicted? Of having, as an accomplice of Cornelius de Witt, concealed the correspondence of the Grand Pensionary and the Marquis de Louvois."

"Well, sir, he was ignorant of this correspondence being deposited with him; completely ignorant. I am as certain as of my life, that, if it were not so, he would have told me; for how could that pure mind have harboured a secret without revealing it to me? No, no, your Highness, I repeat it, and even at the risk of incurring your displeasure, Cornelius is no more guilty of the first crime than of the second; and of the second no more than of the first. Oh, would to Heaven that you knew my Cornelius; Monseigneur!"

"He is a De Witt!" cried Boxtel. "His Highness knows only too much of him, having once granted him his life."

"Silence!" said the Prince; "all these affairs of state, as I have already said, are completely out of the province of the Horticultural Society of Haarlem."

Then, knitting his brow, he added, --

"As to the tulip, make yourself easy, Master Boxtel, you shall have justice done to you."

Boxtel bowed with a heart full of joy, and received the congratulations of the President.

"You, my child," William of Orange continued, "you were going to commit a crime. I will not punish you; but the real evil-doer shall pay the penalty for both. A man of his name may be a conspirator, and even a traitor, but he ought not to be a thief."

"A thief!" cried Rosa. "Cornelius a thief? Pray, your Highness, do not say such a word, it would kill him, if he knew it. If theft there has been, I swear to you, Sir, no one else but this man has committed it."

"Prove it," Boxtel coolly remarked.

"I shall prove it. With God's help I shall."

Then, turning towards Boxtel, she asked, --

"The tulip is yours?"

"It is."

"How many bulbs were there of it?"

Boxtel hesitated for a moment, but after a short consideration he came to the conclusion that she would not ask this question if there were none besides the two bulbs of which he had known already. He therefore answered, --

"Three."

"What has become of these bulbs?"

"Oh! what has become of them? Well, one has failed; the second has produced the black tulip."
