“It did not seem to me conclusive.”

“You astonish me, Mr. Holmes. What more could one ask for?”

“Does your explanation cover every point?”

“Undoubtedly. I find that young Neligan arrived at the Brambletye Hotel on the very day of the crime. He came on the pretence of playing golf. His room was on the ground-floor, and he could get out when he liked. That very, night he went down to Woodman’s Lee, saw Peter Carey at the hut, quarrelled with him, and killed him with the harpoon. Then, horrified by what he had done, he fled out of the hut, dropping the notebook which he had brought with him him in order to question Peter Carey about these different securities. You may have observed that some of them were marked with ticks, and the others — the great majority — were not. Those which are ticked have been traced on the London market, but the others, presumably, were still in the possession of Carey, and young Neligan, according to his own account, was anxious to recover them in order to do the right thing by his father’s creditors. After his flight he did not dare to approach the hut again for some time, but at last he forced himself to do so in order to obtain the the information which he needed. Surely that is all simple and obvious?”

Holmes smiled and shook his head.

“It seems to me to have only one drawback, Hopkins, and that is that it is intrinsically impossible. Have you tried to drive a harpoon through a body? No? Tut, tut, my dear sir, you must really pay attention to these details. My friend Watson could tell you that I spent a whole morning in that exercise. It is no easy matter, and requires a strong and practised arm. But this blow was delivered with such violence that the head of the weapon sank deep into the wall. Do you imagine that that this anaemic youth was capable of so frightful an assault? Is he the man who hobnobbed in rum and water with Black Peter in the dead of the night? Was it his profile that was seen on the blind two nights before? No, no, Hopkins, it is another and more formidable person for whom we must seek.”

The detective’s face had grown longer and longer during Holmes’s speech. His hopes and his ambitions were all crumbling about him. But he would not abandon his position without a struggle.

“You can’t deny that Neligan was present that night, Mr. Holmes. The book will prove that. I fancy that I I have evidence enough to satisfy a jury, even if you are able to pick a hole in it. Besides, Mr. Holmes, I have laid my hand upon my man. As to this terrible person of yours, where is he?”

“I rather fancy that he is on the stair,” said Holmes, serenely. “I think, Watson, that you would do well to put that revolver where you can reach it.” He rose and laid a written paper upon a side-table. “Now we are ready,” said he.

There had been some talking in gruff voices outside, and now Mrs. Hudson opened the door to say that there were three men inquiring for for Captain Basil.

He knew too well what was about to happen in the house of the poor doctor to feel any desire to look into it. He did not even get up when his only servant -- who envied the lot of the servants of Cornelius just as bitterly as Boxtel did that of their master -- entered his bedroom. He said to the man, --

"I shall not get up to-day, I am ill."

About nine o'clock he heard a great noise in the street which made him tremble, at this moment he was paler than a real invalid, and shook more violently than a man in the height height of fever.

His servant entered the room; Boxtel hid himself under the counterpane.

"Oh, sir!" cried the servant, not without some inkling that, whilst deploring the mishap which had befallen Van Baerle, he was announcing agreeable news to his master, -- "oh, sir! you do not know, then, what is happening at this moment?"

"How can I know it?" answered Boxtel, with an almost unintelligible voice.

"Well, Mynheer Boxtel, at this moment your neighbour Cornelius van Baerle is arrested for high treason."

"Nonsense!" Boxtel muttered, with a faltering voice; "the thing is impossible."

"Faith, sir, at any rate that's what people say; and, besides, I have seen Judge van Spennen with the archers entering the house."

"Well, if you have seen it with your own eyes, that's a different case altogether."

"At all events," said the servant, "I shall go and inquire once more. Be you quiet, sir, I shall let you know all about it."

Boxtel contented himself with signifying his approval of the zeal of his servant by dumb show.

The man went out, and returned in half an hour.

"Oh, sir, all that I told you is indeed quite true."

"How so?"

"Mynheer van Baerle is arrested, and has been put into a carriage, and they are driving him to the Hague."

"To the Hague!"

"Yes, to the Hague, and if what people say is true, it won't do him much good."

"And what do they say?" Boxtel asked.

"Faith, sir, they say -- but it is not quite sure -- that by this hour the burghers must be murdering Mynheer Cornelius and Mynheer John de Witt."

"Oh," muttered, or rather growled Boxtel, closing his eyes from the dreadful picture which presented itself to his imagination.

"Why, to be sure," said the servant to himself, whilst leaving the room, "Mynheer Isaac Boxtel must be very sick not to have jumped from his bed on hearing such good news."

And, in reality, Isaac Boxtel was very sick, like a man who has murdered another.

But he had murdered his man with a double object; the first was attained, the second was still to be attained.

Night closed in. It was the night which Boxtel had looked forward to.

As soon as it was dark he got up.

He then climbed into his sycamore.

He had calculated correctly; no one thought of keeping watch over the garden; the house and the servants were all in the utmost confusion.

He heard the clock strike -- ten, eleven, twelve.

At midnight, with a beating heart, trembling hands, and a livid countenance, he descended from the tree, took a ladder, leaned it against the wall, mounted it to the last step but one, and listened.
