“At first the maid thought that young Smith was already dead, but on pouring some water from the carafe over his forehead he opened his eyes for an instant. ‘The professor,’ he murmured — ‘it was she.’ The maid is prepared to swear that those were the exact words. He tried desperately to say something else, and he held his right hand up in the air. Then he fell back dead.

“In the meantime the housekeeper had also arrived upon the scene, but she was just too late to catch the young man’s dying words. Leaving Susan with the body, she hurried to the professor’s room. He was sitting up in bed horribly agitated, for he had heard enough to convince him that something terrible had occurred. Mrs. Marker is prepared to swear that the professor was still in his night-clothes, and indeed it was impossible for him to dress without the help of Mortimer, whose orders were to come at twelve o’clock. The professor declares that he heard the distant cry, but that he knows nothing more. He can give no explanation of the young man’s last words, ‘The professor — it was she,’ but imagines that they were the outcome of delirium. He believes that Willoughby Smith had not an enemy in the world, and can give no reason for the crime. His first action was to send Mortimer, the gardener, for the local police. A A little later the chief constable sent for me. Nothing was moved before I got there, and strict orders were given that no one should walk upon the paths leading to the house. It was a splendid chance of putting your theories into practice, Mr. Sherlock Holmes. There was really nothing wanting.”

“Except Mr. Sherlock Holmes,” said my companion, with a somewhat bitter smile. “Well, let us hear about it. What sort of job did you make of it?”

“I must ask you first, Mr. Holmes, to glance at this rough plan, which will give you a general idea of the position of the professor’s study and the various points of the case. It will help you in following my investigation.”

He unfolded the rough chart, which I here reproduce, and he laid it across Holmes’s knee. I rose and, standing behind Holmes, studied it over his shoulder.

“It is very rough, of course, and it only deals with the points which seem to me to be essential. All the rest you will see later for yourself. Now, first of all, presuming that the assassin entered the house, how did he or she come in? Undoubtedly by the garden path and the back door, from which there is direct access to the study. Any other way would have been exceedingly complicated. The escape must have also been made along that line, for of the two other exits from the room one was blocked by Susan as she ran downstairs and the other leads straight to the professor’s bedroom. I therefore directed my attention at once to the garden path, which was saturated with recent rain, and would certainly show any footmarks.

“My examination showed me that I was dealing with a cautious and expert criminal. No footmarks were to be found on the path. There could be no question, however, that someone had passed along the grass border which lines the path, and that he had done so in order to avoid leaving a track. I could not find anything in the nature of a distinct impression, but the grass was trodden down, and someone had undoubtedly passed. It could only have been the murderer, since neither the gardener nor anyone else had been there that morning, and the rain had only begun during the night.”

"Did not he offer to you tulip bulbs by hundreds?"

"Indeed he did."

"Accept two or three, and, along with them, you may grow the third sucker."

"Yes, that would do very well," said Cornelius, knitting his brow; "if your father were alone, but there is that Master Jacob, who watches all our ways."

"Well, that is true; but only think! you are depriving yourself, as I can easily see, of a very great pleasure."

She pronounced these words with a smile, which was not altogether without a tinge of irony.

Cornelius reflected for a moment; he evidently was struggling against some vehement desire.

"No!" he cried at last, with the stoicism of a Roman of old, "it would be a weakness, it would be a folly, it would be a meanness! If I thus give up the only and last resource which we possess to the uncertain chances of the bad passions of anger and envy, I should never deserve to be forgiven. No, Rosa, no; to-morrow we shall come to a conclusion as to the spot to be chosen for your tulip; you will plant it according to my instructions; and as to the third sucker," -- Cornelius here heaved a deep sigh, -- "watch over it as a miser over his first or last piece of gold; as the mother over her child; as the wounded over the last drop of blood in his veins; watch over it, Rosa! Some voice within me tells me that it will be our saving, that it will be a source of good to us."

"Be easy, Mynheer Cornelius," said Rosa, with a sweet mixture of melancholy and gravity, "be easy; your wishes are commands to me."

"And even," continued Van Baerle, warming more and more with his subject, "if you should perceive that your steps are watched, and that your speech has excited the suspicion of your father and of that detestable Master Jacob, -- well, Rosa, don't hesitate for one moment to sacrifice me, who am only still living through you, -- me, who have no one in the world but you; sacrifice me, -- don't come to see me any more."

Rosa felt her heart sink within her, and her eyes were filling with tears.

"Alas!" she said.

"What is it?" asked Cornelius.

"I see one thing."

"What do you see?"

"I see," said she, bursting out in sobs, "I see that you love your tulips with such love as to have no more room in your heart left for other affections."

Saying this, she fled.

Cornelius, after this, passed one of the worst nights he ever had in his life.

Rosa was vexed with him, and with good reason. Perhaps she would never return to see the prisoner, and then he would have no more news, either of Rosa or of his tulips.

We have to confess, to the disgrace of our hero and of floriculture, that of his two affections he felt most strongly inclined to regret the loss of Rosa; and when, at about three in the morning, he fell asleep overcome with fatigue, and harassed with remorse, the grand black tulip yielded precedence in his dreams to the sweet blue eyes of the fair maid of Friesland.

But poor Rosa, in her secluded chamber, could not have known of whom or of what Cornelius was dreaming.

From what he had said she was more ready to believe that he dreamed of the black tulip than of her; and yet Rosa was mistaken.
