I felt Holmes’s hand steal into mine and give me a reassuring shake, as if to say that the situation was within his powers, and that he was easy in his mind. I was not sure whether he had seen what was only too obvious from my position, that the door of the safe was imperfectly closed, and that Milverton might at any moment observe it. In my own mind I had determined that if I were sure, from the rigidity of his gaze, that it had caught his eye, I would at once spring out, throw my great coat over his head, pinion him, and leave the rest to Holmes. But Milverton never looked up. He was languidly interested by the papers in his hand, and page after page was turned as he followed the argument of the lawyer. At least, I thought, when he has finished the document and the cigar he will go to his room, but before he had reached the end of either, there came a remarkable development which turned our thoughts into quite another channel.

Several times I had observed that Milverton looked at his watch, and once he had risen and sat down again, with a gesture of impatience. The idea, however, that he might have an appointment at so strange an hour never occurred to me until until a faint sound reached my ears from the veranda outside. Milverton dropped his papers and sat rigid in his chair. The sound was repeated, and then there came a gentle tap at the door. Milverton rose and opened it.

“Well,” said he, curtly, “you are nearly half an hour late.”

So this was the explanation of the unlocked door and of the nocturnal vigil of Milverton. There was the gentle rustle of a woman’s dress. I had closed the slit between the curtains as Milverton’s face had turned in our direction, but now I ventured very carefully to open it once more. He had resumed his seat, the cigar still projecting at an insolent angle from the corner of his mouth. In front of him, in the full glare of the electric light, there stood a tall, slim, dark woman, a veil over her face, a mantle drawn round her chin. Her breath came quick and fast, and every inch of the lithe figure was quivering with strong emotion.

“Well,” said Milverton, “you made me lose a good night’s rest, my dear. I hope you’ll prove worth it. You couldn’t come any other time — eh?”

The woman shook her head.

“Well, if you couldn’t you couldn’t. If the Countess is a hard mistress, you have your chance to get level with her now. Bless the girl, what are you shivering about? That’s right. Pull yourself together. Now, let us get down to business.” He took a notebook from the drawer of his desk. “You say that you have five letters which compromise the Countess d’Albert. You want to sell them. I want to buy them. So far so good. It only remains to fix a price. I should want to inspect the letters, of course. If they are really good specimens — Great heavens, is it you?”

The woman, without a word, had raised her veil and dropped the mantle from her chin. It was a dark, handsome, clear-cut face which confronted Milverton — a face with a curved nose, strong, dark eyebrows shading hard, glittering eyes, and a straight, thin-lipped mouth set in a dangerous smile.

The dog perhaps knew the condemned prisoners, and only bit those who left as free men.

The shorter the way from the door of the prison to the foot of the scaffold, the more fully, of course, it was crowded with curious people.

These were the same who, not satisfied with the blood which they had shed three days before, were now craving for a new victim.

And scarcely had Cornelius made his appearance than a fierce groan ran through the whole street, spreading all over the yard, and re-echoing from the streets which led to the scaffold, and which were likewise crowded with spectators.

The scaffold indeed looked like an islet at the confluence of several rivers.

In the midst of these threats, groans, and yells, Cornelius, very likely in order not to hear them, had buried himself in his own thoughts.

And what did he think of in his last melancholy journey?

Neither of his enemies, nor of his judges, nor of his executioners.

He thought of the beautiful tulips which he would see from heaven above, at Ceylon, or Bengal, or elsewhere, when he would be able to look with pity on this earth, where John and Cornelius de Witt had been murdered for having thought too much of politics, and where Cornelius van Baerle was about to be murdered for having thought too much of tulips.

"It is only one stroke of the axe," said the philosopher to himself, "and my beautiful dream will begin to be realised."

Only there was still a chance, just as it had happened before to M. de Chalais, to M. de Thou, and other slovenly executed people, that the headsman might inflict more than one stroke, that is to say, more than one martyrdom, on the poor tulip-fancier.

Yet, notwithstanding all this, Van Baerle mounted the scaffold not the less resolutely, proud of having been the friend of that illustrious John, and godson of that noble Cornelius de Witt, whom the ruffians, who were now crowding to witness his own doom, had torn to pieces and burnt three days before.

He knelt down, said his prayers, and observed, not without a feeling of sincere joy, that, laying his head on the block, and keeping his eyes open, he would be able to his last moment to see the grated window of the Buytenhof.

At length the fatal moment arrived, and Cornelius placed his chin on the cold damp block. But at this moment his eyes closed involuntarily, to receive more resolutely the terrible avalanche which was about to fall on his head, and to engulf his life.

A gleam like that of lightning passed across the scaffold: it was the executioner raising his sword.

Van Baerle bade farewell to the great black tulip, certain of awaking in another world full of light and glorious tints.

Three times he felt, with a shudder, the cold current of air from the knife near his neck, but what a surprise! he felt neither pain nor shock.

He saw no change in the colour of the sky, or of the world around him.

Then suddenly Van Baerle felt gentle hands raising him, and soon stood on his feet again, although trembling a little.

He looked around him. There was some one by his side, reading a large parchment, sealed with a huge seal of red wax.
