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 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.
All was perfectly quiet, not a sound broke the silence of the night; one solitary light, that of the housekeeper, was burning in the house.
This silence and this darkness emboldened Boxtel; he got astride the wall, stopped for an instant, and, after having ascertained that there was nothing to fear, he put his ladder from his own garden into that of Cornelius, and descended.
Then, knowing to an inch where the bulbs which were to produce the black tulip were planted, he ran towards the spot, following, however, the gravelled walks in order not to be betrayed by his footprints, and, on arriving at the precise spot, he proceeded, with the eagerness of a tiger, to plunge his hand into the soft ground.
He found nothing, and thought he was mistaken.
In the meanwhile, the cold sweat stood on his brow.
He felt about close by it,--nothing.
He felt about on the right, and on the left,--nothing.
He felt about in front and at the back,--nothing.
He was nearly mad, when at last he satisfied himself that on that very morning the earth had been disturbed.
In fact, whilst Boxtel was lying in bed, Cornelius had gone down to his garden, had taken up the mother bulb, and, as we have seen, divided it into three.
Boxtel could not bring himself to leave the place.

He dug up with his hands more than ten square feet of ground.
At last no doubt remained of his misfortune.

Mad with rage, he returned to his ladder, mounted the wall, drew up the ladder, flung it into his own garden, and jumped after it.
All at once, a last ray of hope presented itself to his mind: the seedling bulbs might be in the dry-room; it was therefore only requisite to make his entry there as he had done into the garden.
There he would find them, and, moreover, it was not at all difficult, as the sashes of the dry-room might be raised like those of a greenhouse.
Cornelius had opened them on that morning, and no one had thought of closing them again.
Everything, therefore, depended upon whether he could procure a ladder of sufficient length,--one of twenty-five feet instead of ten.
Boxtel had noticed in the street where he lived a house which was being repaired, and against which a very tall ladder was placed.
This ladder would do admirably, unless the workmen had taken it away.
He ran to the house: the ladder was there.
