And yet it must be said, to the disgrace of mankind, that Cornelius van Baerle, without being aware of the fact, had a much more ferocious, fierce, and implacable enemy than the Grand Pensionary and his brother had among the Orange party, who were most hostile to the devoted brothers, who had never been sundered by the least misunderstanding during their lives, and by their mutual devotion in the face of death made sure the existence of their brotherly affection beyond the grave.

At the time when Cornelius van Baerle began to devote himself to tulip-growing, expending on this hobby his yearly revenue and the guilders of his father, there was at Dort, living next door to him, a citizen of the name of Isaac Boxtel who from the age when he was able to think for himself had indulged the same fancy, and who was in ecstasies at the mere mention of the word "tulban," which (as we are assured by the "Floriste Francaise," the most highly considered authority in matters relating to this flower) is the first word in the Cingalese tongue which was ever used to designate that masterpiece of floriculture which is now called the tulip.

Boxtel had not the good fortune of being rich, like Van Baerle. He had therefore, with great care and patience, and by dint of strenuous strenuous exertions, laid out near his house at Dort a garden fit for the culture of his cherished flower; he had mixed the soil according to the most approved prescriptions, and given to his hotbeds just as much heat and fresh air as the strictest rules of horticulture exact.

Isaac knew the temperature of his frames to the twentieth part of a degree. He knew the strength of the current of air, and tempered it so as to adapt it to the wave of the stems of his flowers. His productions also began to meet with the favour of the public. They were beautiful, nay, distinguished. Several fanciers had come to see Boxtel's tulips. At last he had even started amongst all the Linnaeuses and Tourneforts a tulip which bore his name, and which, after having travelled all through France, had found its way into Spain, and penetrated as far as Portugal; and the King, Don Alfonso VI. -- who, being expelled from Lisbon, had retired to the island of Terceira, where he amused himself, not, like the great Conde, with watering his carnations, but with growing tulips -- had, on seeing the Boxtel tulip, exclaimed, "Not so bad, by any means!"

All at once, Cornelius van Baerle, who, after all his learned pursuits, had been seized with the tulipomania, made some changes in his house at Dort, which, as we have stated, was next door to that of Boxtel. He raised a certain building in his court-yard by a story, which shutting out the sun, took half a degree of warmth from Boxtel's garden, and, on the other hand, added half a degree of cold in winter; not to mention that it cut the wind, and disturbed all the horticultural calculations and arrangements of his neighbour.

After all, this mishap appeared to Boxtel of no great consequence. Van Baerle was but a painter, a sort of fool who tried to reproduce and disfigure on canvas the wonders of nature. The painter, he thought, had raised his studio by a story to get better light, and thus far he had only been in the right. Mynheer van Baerle was a painter, as Mynheer Boxtel was a tulip-grower; he wanted somewhat more sun for his paintings, and he took half a degree from his neighbour's tulips.

“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.”
