“The absence of the latter means nothing, though its presence may mean everything,” said Holmes. “Unless the powder from a badly fitting cartridge happens to spurt backward, one may fire many shots without leaving a sign. I would suggest that Mr. Cubitt’s body may now be removed. I suppose, Doctor, you have not recovered the bullet which wounded the lady?”

“A serious operation will be necessary before that can be done. But there are still four cartridges in the revolver. Two have been fired and two wounds inflicted, so that each bullet can be accounted for.”

“So it would seem,” said Holmes. “Perhaps you can account also for the bullet which has so obviously struck the edge of the window?”

He had turned suddenly, and his long, thin finger was pointing to a hole which had been drilled right through the lower window-sash, about an inch above the bottom.

“By George!” cried the inspector. “How ever did you see that?”

“Because I looked for it.”

“Wonderful!” said the country doctor. “You are certainly right, sir. Then a third shot has been fired, and therefore a third person must have been present. But who could that have been, and how could he have got away?”

“That is the problem which we are now about to solve,” said Sherlock Holmes. “You remember, Inspector Martin, when the servants said that on leaving their room room they were at once conscious of a smell of powder, I remarked that the point was an extremely important one?”

“Yes, sir; but I confess I did not quite follow you.”

“It suggested that at the time of the firing, the window as well as the door of the room had been open. Otherwise the fumes of powder could not have been blown so rapidly through the house. A draught in the room was necessary for that. Both door and window were only open for a very short time, however.”

“How do you prove that?”

“Because the candle was not guttered.”

“Capital!” cried the inspector. “Capital!”

“Feeling sure that the window had been open at the time of the tragedy, I conceived that there might have been a third person in the affair, who stood outside this opening and fired through it. Any shot directed at this person might hit the sash. I looked, and there, sure enough, was the bullet mark!”

“But how came the window to be shut and fastened?”

“The woman’s first instinct would be to shut and fasten the window. But, halloa! what is this?”

It was a lady’s hand-bag which stood upon the study table — a trim little handbag of crocodile-skin and silver. Holmes opened it and turned the contents out. There were twenty fifty-pound notes of the Bank of England, held together by an india-rubber band — nothing else.

“This must be preserved, for it will figure in the trial,” said Holmes, as he handed the bag with its contents to the inspector. “It is now necessary that we should try to throw some light upon this third bullet, which has clearly, from the splintering of the wood, been fired from inside the room. I should like to see Mrs. King, the cook, again. You said, Mrs. King, that you were awakened by a loud explosion. When you said that, did you mean that it seemed to you to be louder than the second one?”

In the meanwhile the sentence had been pronounced. Thus Isaac had no more time to bribe any one. He therefore clung to the idea which Rosa had suggested: he went to the executioner.

Isaac had not the least doubt that Cornelius would die with the bulbs on his heart.

But there were two things which Boxtel did not calculate upon: --

Rosa, that is to say, love;

William of Orange, that is to say, clemency.

But for Rosa and William, the calculations of the envious neighbour would have been correct.

But for William, Cornelius would have died.

But for Rosa, Cornelius would have died with his bulbs on his heart.

Mynheer Boxtel went to the headsman, to whom he gave himself out as a great friend of the condemned man; and from whom he bought all the clothes of the dead man that was to be, for one hundred guilders; rather an exorbitant sum, as he engaged to leave all the trinkets of gold and silver to the executioner.

But what was the sum of a hundred guilders to a man who was all but sure to buy with it the prize of the Haarlem Society?

It was money lent at a thousand per cent., which, as nobody will deny, was a very handsome investment.

The headsman, on the other hand, had scarcely anything to do to earn his hundred guilders. He needed only, as soon as the execution was over, to allow Mynheer Boxtel to ascend the scaffold with his servants, to remove the inanimate remains of his friend.

The thing was, moreover, quite customary among the "faithful brethren," when one of their masters died a public death in the yard of the Buytenhof.

A fanatic like Cornelius might very easily have found another fanatic who would give a hundred guilders for his remains.

The executioner also readily acquiesced in the proposal, making only one condition, -- that of being paid in advance.

Boxtel, like the people who enter a show at a fair, might be disappointed, and refuse to pay on going out.

Boxtel paid in advance, and waited.

After this, the reader may imagine how excited Boxtel was; with what anxiety he watched the guards, the Recorder, and the executioner; and with what intense interest he surveyed the movements of Van Baerle. How would he place himself on the block? how would he fall? and would he not, in falling, crush those inestimable bulbs? had not he at least taken care to enclose them in a golden box, -- as gold is the hardest of all metals?

Every trifling delay irritated him. Why did that stupid executioner thus lose time in brandishing his sword over the head of Cornelius, instead of cutting that head off?

But when he saw the Recorder take the hand of the condemned, and raise him, whilst drawing forth the parchment from his pocket, -- when he heard the pardon of the Stadtholder publicly read out, -- then Boxtel was no more like a human being; the rage and malice of the tiger, of the hyena, and of the serpent glistened in his eyes, and vented itself in his yell and his movements. Had he been able to get at Van Baerle, he would have pounced upon him and strangled him.

And so, then, Cornelius was to live, and was to go with him to Loewestein, and thither to his prison he would take with him his bulbs; and perhaps he would even find a garden where the black tulip would flower for him.
