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 never occurred to me 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.

"Of a tumult?" replied Cornelius, fixing his eyes on his perplexed brother; "a tumult?"

"Yes, Cornelius."

"Oh! that's what I heard just now," said the prisoner, as if speaking to himself. Then, turning to his brother, he continued, --

"Are there many persons down before the prison."

"Yes, my brother, there are."

"But then, to come here to me ---- "

"Well?"

"How is it that they have allowed you to pass?"

"You know well that we are not very popular, Cornelius," said the Grand Pensionary, with gloomy bitterness. "I have made my way through all sorts of bystreets and alleys."

"You hid yourself, John?"

"I wished to reach you without loss of time, and I did what people will do in politics, or on the sea when the wind is against them, -- I tacked."

At this moment the noise in the square below was heard to roar with increasing fury. Tilly was parleying with the burghers.

"Well, well," said Cornelius, "you are a very skilful pilot, John; but I doubt whether you will as safely guide your brother out of the Buytenhof in the midst of this gale, and through the raging surf of popular hatred, as you did the fleet of Van Tromp past the shoals of the Scheldt to Antwerp."

"With the help of God, Cornelius, we'll at least try," answered John; "but, first of all, a word with you."

"Speak!"

The shouts began anew.

"Hark, hark!" continued Cornelius, "how angry those people are! Is it against you, or against me?"

"I should say it is against us both, Cornelius. I told you, my dear brother, that the Orange party, while assailing us with their absurd calumnies, have also made it a reproach against us that we have negotiated with France."

"What blockheads they are!"

"But, indeed, they reproach us with it."

"And yet, if these negotiations had been successful, they would have prevented the defeats of Rees, Orsay, Wesel, and Rheinberg; the Rhine would not have been crossed, and Holland might still consider herself invincible in the midst of her marshes and canals."

"All this is quite true, my dear Cornelius, but still more certain it is, that if at this moment our correspondence with the Marquis de Louvois were discovered, skilful pilot as I am, I should not be able to save the frail barque which is to carry the brothers De Witt and their fortunes out of Holland. That correspondence, which might prove to honest people how dearly I love my country, and what sacrifices I have offered to make for its liberty and glory, would be ruin to us if it fell into the hands of the Orange party. I hope you have burned the letters before you left Dort to join me at the Hague."

"My dear brother," Cornelius answered, "your correspondence with M. de Louvois affords ample proof of your having been of late the greatest, most generous, and most able citizen of the Seven United Provinces. I rejoice in the glory of my country; and particularly do I rejoice in your glory, John. I have taken good care not to burn that correspondence."

"Then we are lost, as far as this life is concerned," quietly said the Grand Pensionary, approaching the window.
