They then searched the sheets, the mattress, and the straw mattress of his bed; and again they found nothing.

Now, Cornelius rejoiced that he had not taken the third sucker under his own care. Gryphus would have been sure to ferret it out in the search, and would then have treated it as he did the first.

And certainly never did prisoner look with greater complacency at a search made in his cell than Cornelius.

Gryphus retired with the pencil and the two or three leaves of white paper which Rosa had given to Van Baerle, this was the only trophy brought back from the expedition.

At six Gryphus came back again, but alone; Cornelius tried to propitiate him, but Gryphus growled, showed a large tooth like a tusk, which he had in the corner of his mouth, and went out backwards, like a man who is afraid of being attacked from behind.

Cornelius burst out laughing, to which Gryphus answered through the grating, --

"Let him laugh that wins."

The winner that day was Cornelius; Rosa came at nine.

She was without a lantern. She needed no longer a light, as she could now read. Moreover, the light might betray her, as Jacob was dogging her steps more than ever. And lastly, the light would would have shown her blushes.

Of what did the young people speak that evening? Of those matters of which lovers speak at the house doors in France, or from a balcony into the street in Spain, or down from a terrace into a garden in the East.

They spoke of those things which give wings to the hours; they spoke of everything except the black tulip.

At last, when the clock struck ten, they parted as usual.

Cornelius was happy, as thoroughly happy as a tulip-fancier would be to whom one has not spoken of his tulip.

He found Rosa pretty, good, graceful, and charming.

But why did Rosa object to the tulip being spoken of?

This was indeed a great defect in Rosa.

Cornelius confessed to himself, sighing, that woman was not perfect.

Part of the night he thought of this imperfection; that is to say, so long as he was awake he thought of Rosa.

After having fallen asleep, he dreamed of her.

But the Rosa of his dreams was by far more perfect than the Rosa of real life. Not only did the Rosa of his dreams speak of the tulip, but also brought to him a black one in a china vase.

Cornelius then awoke, trembling with joy, and muttering, --

"Rosa, Rosa, I love you."

And as it was already day, he thought it right not to fall asleep again, and he continued following up the line of thought in which his mind was engaged when he awoke.

Ah! if Rosa had only conversed about the tulip, Cornelius would have preferred her to Queen Semiramis, to Queen Cleopatra, to Queen Elizabeth, to Queen Anne of Austria; that is to say, to the greatest or most beautiful queens whom the world has seen.

But Rosa had forbidden it under pain of not returning; Rosa had forbidden the least mention of the tulip for three days. That meant seventy-two hours given to the lover to be sure; but it was seventy-two hours stolen from the horticulturist.

“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.”
