Thus Haarlem was thrice given over to rejoicing, for a three-fold celebration was to take place.

In the first place, the black tulip had been produced; secondly, the Prince William of Orange, as a true Hollander, had promised to be present at the ceremony of its inauguration; and, thirdly, it was a point of honour with the States to show to the French, at the conclusion of such a disastrous war as that of 1672, that the flooring of the Batavian Republic was solid enough for its people to dance on it, with the accompaniment of the cannon of their fleets.

The Horticultural Society of Haarlem had shown shown itself worthy of its fame by giving a hundred thousand guilders for the bulb of a tulip. The town, which did not wish to be outdone, voted a like sum, which was placed in the hands of that notable body to solemnise the auspicious event.

And indeed on the Sunday fixed for this ceremony there was such a stir among the people, and such an enthusiasm among the townsfolk, that even a Frenchman, who laughs at everything at all times, could not have helped admiring the character of those honest Hollanders, who were equally ready to spend their money for the construction of a man-of-war -- that that is to say, for the support of national honour -- as they were to reward the growth of a new flower, destined to bloom for one day, and to serve during that day to divert the ladies, the learned, and the curious.

At the head of the notables and of the Horticultural Committee shone Mynheer van Systens, dressed in his richest habiliments.

The worthy man had done his best to imitate his favourite flower in the sombre and stern elegance of his garments; and we are bound to record, to his honour, that he had perfectly succeeded in his object.

Dark crimson velvet, dark purple silk, and jet-black cloth, cloth with linen of dazzling whiteness, composed the festive dress of the President, who marched at the head of his Committee carrying an enormous nosegay, like that which a hundred and twenty-one years later, Monsieur de Robespierre displayed at the festival of "The Supreme Being."

There was, however, a little difference between the two; very different from the French tribune, whose heart was so full of hatred and ambitious vindictiveness, was the honest President, who carried in his bosom a heart as innocent as the flowers which he held in his hand.

Behind the Committee, who were as gay as a meadow, and as fragrant as a garden garden in spring, marched the learned societies of the town, the magistrates, the military, the nobles and the boors.

The people, even among the respected republicans of the Seven Provinces, had no place assigned to them in the procession; they merely lined the streets.

This is the place for the multitude, which with true philosophic spirit, waits until the triumphal pageants have passed, to know what to say of them, and sometimes also to know what to do.

This time, however, there was no question either of the triumph of Pompey or of Caesar; neither of the defeat of Mithridates, nor of the conquest of Gaul. The procession was as as placid as the passing of a flock of lambs, and as inoffensive as a flight of birds sweeping through the air.

“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 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.”
