“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 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 information which he needed. Surely that is all simple and obvious?”

Holmes smiled and shook his head.

“It seems to me to have 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 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 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 Captain Basil.

And, besides, if the parcel had been made up of bulbs, Boxtel knew his neighbour too well not to expect that Van Baerle would not have lost one moment in satisfying his curiosity and feasting his eyes on the present which he had received.

But, on the contrary, Cornelius had received the parcel from the hands of his godfather with every mark of respect, and put it by with the same respectful manner in a drawer, stowing it away so that it should not take up too much of the room which was reserved to his bulbs.

The parcel thus being secreted, Cornelius de Witt got up, pressed the hand of his godson, and turned towards the door, Van Baerle seizing the candlestick, and lighting him on his way down to the street, which was still crowded with people who wished to see their great fellow citizen getting into his coach.

Boxtel had not been mistaken in his supposition. The deposit intrusted to Van Baerle, and carefully locked up by him, was nothing more nor less than John de Witt's correspondence with the Marquis de Louvois, the war minister of the King of France; only the godfather forbore giving to his godson the least intimation concerning the political importance of the secret, merely desiring him not to deliver the parcel to any one but to himself, or to whomsoever he should send to claim it in his name.

And Van Baerle, as we have seen, locked it up with his most precious bulbs, to think no more of it, after his godfather had left him; very unlike Boxtel, who looked upon this parcel as a clever pilot does on the distant and scarcely perceptible cloud which is increasing on its way and which is fraught with a storm.

Little dreaming of the jealous hatred of his neighbour, Van Baerle had proceeded step by step towards gaining the prize offered by the Horticultural Society of Haarlem. He had progressed from hazel-nut shade to that of roasted coffee, and on the very day when the frightful events took place at the Hague which we have related in the preceding chapters, we find him, about one o'clock in the day, gathering from the border the young suckers raised from tulips of the colour of roasted coffee; and which, being expected to flower for the first time in the spring of 1675, would undoubtedly produce the large black tulip required by the Haarlem Society.

On the 20th of August, 1672, at one o'clock, Cornelius was therefore in his dry-room, with his feet resting on the foot-bar of the table, and his elbows on the cover, looking with intense delight on three suckers which he had just detached from the mother bulb, pure, perfect, and entire, and from which was to grow that wonderful produce of horticulture which would render the name of Cornelius van Baerle for ever illustrious.

"I shall find the black tulip," said Cornelius to himself, whilst detaching the suckers. "I shall obtain the hundred thousand guilders offered by the Society. I shall distribute them among the poor of Dort; and thus the hatred which every rich man has to encounter in times of civil wars will be soothed down, and I shall be able, without fearing any harm either from Republicans or Orangists, to keep as heretofore my borders in splendid condition. I need no more be afraid lest on the day of a riot the shopkeepers of the town and the sailors of the port should come and tear out my bulbs, to boil them as onions for their families, as they have sometimes quietly threatened when they happened to remember my having paid two or three hundred guilders for one bulb. It is therefore settled I shall give the hundred thousand guilders of the Haarlem prize to-the poor. And yet ---- "
