And also, if Dante had wished for a new type to be added to his characters of the Inferno, he might have chosen Boxtel during the period of Van Baerle's successes. Whilst Cornelius was weeding, manuring, watering his beds, whilst, kneeling on the turf border, he analysed every vein of the flowering tulips, and meditated on the modifications which might be effected by crosses of colour or otherwise, Boxtel, concealed behind a small sycamore which he had trained at the top of the partition wall in the shape of a fan, watched, with his eyes starting from their sockets and with foaming mouth, every step and every gesture gesture of his neighbour; and whenever he thought he saw him look happy, or descried a smile on his lips, or a flash of contentment glistening in his eyes, he poured out towards him such a volley of maledictions and furious threats as to make it indeed a matter of wonder that this venomous breath of envy and hatred did not carry a blight on the innocent flowers which had excited it.

When the evil spirit has once taken hold of the heart of man, it urges him on, without letting him stop. Thus Boxtel soon was no longer content with seeing Van Baerle. He wanted to see his flowers, flowers too; he had the feelings of an artist, the master-piece of a rival engrossed his interest.

He therefore bought a telescope, which enabled him to watch as accurately as did the owner himself every progressive development of the flower, from the moment when, in the first year, its pale seed-leaf begins to peep from the ground, to that glorious one, when, after five years, its petals at last reveal the hidden treasures of its chalice. How often had the miserable, jealous man to observe in Van Baerle's beds tulips which dazzled him by their beauty, and almost choked him by their perfection!

And then, after the first blush of the the admiration which he could not help feeling, he began to be tortured by the pangs of envy, by that slow fever which creeps over the heart and changes it into a nest of vipers, each devouring the other and ever born anew. How often did Boxtel, in the midst of tortures which no pen is able fully to describe, -- how often did he feel an inclination to jump down into the garden during the night, to destroy the plants, to tear the bulbs with his teeth, and to sacrifice to his wrath the owner himself, if he should venture to stand up for the defence of his his tulips!

But to kill a tulip was a horrible crime in the eyes of a genuine tulip-fancier; as to killing a man, it would not have mattered so very much.

Yet Van Baerle made such progress in the noble science of growing tulips, which he seemed to master with the true instinct of genius, that Boxtel at last was maddened to such a degree as to think of throwing stones and sticks into the flower-stands of his neighbour. But, remembering that he would be sure to be found out, and that he would not only be punished by law, but also dishonoured for ever in the face of all the the tulip-growers of Europe, he had recourse to stratagem, and, to gratify his hatred, tried to devise a plan by means of which he might gain his ends without being compromised himself.

“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 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.”
