On the 20th of August, 1672, the city of the Hague, always so lively, so neat, and so trim that one might believe every day to be Sunday, with its shady park, with its tall trees, spreading over its Gothic houses, with its canals like large mirrors, in which its steeples and its almost Eastern cupolas are reflected, -- the city of the Hague, the capital of the Seven United Provinces, was swelling in all its arteries with a black and red stream of hurried, panting, and restless citizens, who, with their knives in their girdles, muskets on their shoulders, or sticks in their hands, were pushing on to the Buytenhof, a terrible prison, the grated windows of which are still shown, where, on the charge of attempted murder preferred against him by the surgeon Tyckelaer, Cornelius de Witt, the brother of the Grand Pensionary of Holland was confined.

If the history of that time, and especially that of the year in the middle of which our narrative commences, were not indissolubly connected with the two names just mentioned, the few explanatory pages which we are about to add might appear quite supererogatory; but we will, from the very first, apprise the reader -- our old friend, to whom we are wont on the first page to promise amusement, and and with whom we always try to keep our word as well as is in our power -- that this explanation is as indispensable to the right understanding of our story as to that of the great event itself on which it is based.

Cornelius de Witt, Ruart de Pulten, that is to say, warden of the dikes, ex-burgomaster of Dort, his native town, and member of the Assembly of the States of Holland, was forty-nine years of age, when the Dutch people, tired of the Republic such as John de Witt, the Grand Pensionary of Holland, understood it, at once conceived a most violent affection for the Stadtholderate, which had been abolished for ever in Holland by the "Perpetual Edict" forced by John de Witt upon the United Provinces.

As it rarely happens that public opinion, in its whimsical flights, does not identify a principle with a man, thus the people saw the personification of the Republic in the two stern figures of the brothers De Witt, those Romans of Holland, spurning to pander to the fancies of the mob, and wedding themselves with unbending fidelity to liberty without licentiousness, and prosperity without the waste of superfluity; on the other hand, the Stadtholderate recalled to the popular mind the grave and thoughtful image of the young Prince William of Orange.

The brothers De Witt humoured Louis XIV., whose moral influence was felt by the whole of Europe, and the pressure of whose material power Holland had been made to feel in that marvellous campaign on the Rhine, which, in the space of three months, had laid the power of the United Provinces prostrate.

Louis XIV. had long been the enemy of the Dutch, who insulted or ridiculed him to their hearts' content, although it must be said that they generally used French refugees for the mouthpiece of their spite. Their national pride held him up as the Mithridates of the Republic. The brothers De Witt, therefore, had to strive against a double difficulty, -- against the force of national antipathy, and, besides, against the feeling of weariness which is natural to all vanquished people, when they hope that a new chief will be able to save them from ruin and shame.

“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.”
