The judge summed up with the following dilemma: --

"Either Cornelius van Baerle is a great lover of tulips, or a great lover of politics; in either case, he has told us a falsehood; first, because his having occupied himself with politics is proved by the letters which were found at his house; and secondly, because his having occupied himself with tulips is proved by the bulbs which leave no doubt of the fact. And herein lies the enormity of the case. As Cornelius van Baerle was concerned in the growing of tulips and in the pursuit of politics at one and the same time, the prisoner is of hybrid character, of an amphibious organisation, working with equal ardour at politics and at tulips, which proves him to belong to the class of men most dangerous to public tranquillity, and shows a certain, or rather a complete, analogy between his character and that of those master minds of which Tarquin the Elder and the Great Conde have been felicitously quoted as examples."

The upshot of all these reasonings was, that his Highness the Prince Stadtholder of Holland would feel infinitely obliged to the magistracy of the Hague if they simplified for him the government of the Seven Provinces by by destroying even the least germ of conspiracy against his authority.

This argument capped all the others, and, in order so much the more effectually to destroy the germ of conspiracy, sentence of death was unanimously pronounced against Cornelius van Baerle, as being arraigned, and convicted, for having, under the innocent appearance of a tulip-fancier, participated in the detestable intrigues and abominable plots of the brothers De Witt against Dutch nationality and in their secret relations with their French enemy.

A supplementary clause was tacked to the sentence, to the effect that "the aforesaid Cornelius van Baerle should be led from the prison of the Buytenhof to the scaffold in the yard of the same name, where the public executioner would cut off his head."

As this deliberation was a most serious affair, it lasted a full half-hour, during which the prisoner was remanded to his cell.

There the Recorder of the States came to read the sentence to him.

Master Gryphus was detained in bed by the fever caused by the fracture of his arm. His keys passed into the hands of one of his assistants. Behind this turnkey, who introduced the Recorder, Rosa, the fair Frisian maid, had slipped into the recess of the door, with a handkerchief to her mouth to stifle her sobs.

Cornelius listened to the sentence with an expression rather of surprise than sadness.

After the sentence was read, the Recorder asked him whether he had anything to answer.

"Indeed, I have not," he replied. "Only I confess that, among all the causes of death against which a cautious man may guard, I should never have supposed this to be comprised."

On this answer, the Recorder saluted Van Baerle with all that consideration which such functionaries generally bestow upon great criminals of every sort.

But whilst he was about to withdraw, Cornelius asked, "By the bye, Mr. Recorder, what day is the thing -- you know what I mean -- to take place?"

“Yes, it was by their light, and that of the lady’s bedroom candle, that the burglars saw their way about.”

“And what did they take?”

“Well, they did not take much — only half a dozen articles of plate off the sideboard. Lady Brackenstall thinks that they were themselves so disturbed by the death of Sir Eustace that they did not ransack the house, as they would otherwise have done.”

“No doubt that is true, and yet they drank some wine, I understand.”

“To steady their nerves.”

“Exactly. These three glasses upon the sideboard have been untouched, I suppose?”

“Yes, and the bottle stands as they left it.”

“Let us look at it. Halloa, halloa! What is this?”

The three glasses were grouped together, all of them tinged with wine, and one of them containing some dregs of beeswing. The bottle stood near them, two-thirds full, and beside it lay a long, deeply stained cork. Its appearance and the dust upon the bottle showed that it was no common vintage which the murderers had enjoyed.

A change had come over Holmes’s manner. He had lost his listless expression, and again I saw an alert light of interest in his keen, deep-set eyes. He raised the cork and examined it minutely.

“How did they draw it?” he asked.

Hopkins pointed to a half-opened drawer. In it lay some table linen and a large corkscrew.

“Did Lady Brackenstall say that screw was used?”

“No, you remember that she was senseless at the moment when the bottle was opened.”

“Quite so. As a matter of fact, that screw was not used. This bottle was opened by a pocket screw, probably contained in a knife, and not more than an inch and a half long. If you will examine the top of the cork, you will observe that the screw was driven in three times before the cork was extracted. It has never been transfixed. This long screw would have transfixed it and drawn it up with a single pull. When you catch this fellow, you will find that he has one of these multiplex knives in his possession.”

“Excellent!” said Hopkins.

“But these glasses do puzzle me, I confess. Lady Brackenstall actually saw the three men drinking, did she not?”

“Yes; she was clear about that.”

“Then there is an end of it. What more is to be said? And yet, you must admit, that the three glasses are very remarkable, Hopkins. What? You see nothing remarkable? Well, well, let it pass. Perhaps, when a man has special knowledge and special powers like my own, it rather encourages him to seek a complex explanation when a simpler one is at hand. Of course, it must be a mere chance about the glasses. Well, good-morning, Hopkins. I don’t see that I can be of any use to you, and you appear to have your case very clear. You will let me know when Randall is arrested, and any further developments which may occur. I trust that I shall soon have to congratulate you upon a successful conclusion. Come, Watson, I fancy that we may employ ourselves more profitably at home.”
