“A simple case, and yet, in some ways, an instructive one,” Holmes remarked, as we travelled back to town. “It hinged from the outset upon the pince-nez. But for the fortunate chance of the dying man having seized these, I am not sure that we could ever have reached our solution. It was clear to me, from the strength of the glasses, that the wearer must have been very blind and helpless when deprived of them. When you asked me to believe that she walked along a narrow strip of grass without once making a false step, I remarked, as you may remember, that it was a noteworthy performance. In my mind I set it down as an impossible performance, save in the unlikely case that she had a second pair of glasses. I was forced, therefore, to consider seriously the hypothesis that she had remained within the house. On perceiving the similarity of the two corridors, it became clear that she might very easily have made such a mistake, and, in that case, it was evident that she must have entered the professor’s room. I was keenly on the alert, therefore, for whatever would bear out this supposition, and I examined the room narrowly for anything in the shape of a hiding-place. The carpet seemed continuous and firmly nailed, so I dismissed the idea of a trap-door. There might might well be a recess behind the books. As you are aware, such devices are common in old libraries. I observed that books were piled on the floor at all other points, but that one bookcase was left clear. This, then, might be the door. I could see no marks to guide me, but the carpet was of a dun colour, which lends itself very well to examination. I therefore smoked a great number of those excellent cigarettes, and I dropped the ash all over the space in front of the suspected bookcase. It was a simple trick, but exceedingly effective. I then went downstairs, and I ascertained, in your presence, Watson, without your perceiving the drift of my remarks, that Professor Coram’s consumption of food had increased — as one would expect when he is supplying a second person. We then ascended to the room again, when, by upsetting the cigarette-box, I obtained a very excellent view of the floor, and was able to see quite clearly, from the traces upon the cigarette ash, that the prisoner had in our absence come out from her retreat. Well Hopkins, here we are at Charing Cross, and I congratulate you on having brought your case to a successful conclusion. You are going to headquarters, no doubt. I think, Watson, you and I will drive together to the Russian Embassy.”

We were fairly accustomed to receive weird telegrams at Baker Street, but I have a particular recollection of one which reached us on a gloomy February morning, some seven or eight years ago, and gave Mr. Sherlock Holmes a puzzled quarter of an hour. It was addressed to him, and ran thus:

Please await me. Terrible misfortune. Right wing threequarter missing, indispensable to-morrow.

OVERTON.

“Strand postmark, and dispatched ten thirty-six,” said Holmes, reading it over and over. “Mr. Overton was evidently considerably excited when he sent it, and somewhat incoherent in consequence. Well, well, he will be here, I daresay, by the time I have looked through the Times, and then we shall know all about it. Even the most insignificant problem would be welcome in these stagnant days.”

In the meanwhile, a great noise was heard, like the distant roar of the sea, at the other extremity of the market-place. People were running about, doors opening and shutting, Rosa alone was unconscious of all this hubbub among the multitude.

"We must return to the President," she muttered.

"Well, then, let us return," said the boatman.

They took a small street, which led them straight to the mansion of Mynheer van Systens, who with his best pen in his finest hand continued to draw up his report.

Everywhere on her way Rosa heard people speaking only of the black tulip, and the prize of a hundred thousand guilders. The news had spread like wildfire through the town.

Rosa had not a little difficulty is penetrating a second time into the office of Mynheer van Systens, who, however, was again moved by the magic name of the black tulip.

But when he recognised Rosa, whom in his own mind he had set down as mad, or even worse, he grew angry, and wanted to send her away.

Rosa, however, clasped her hands, and said with that tone of honest truth which generally finds its way to the hearts of men, --

"For Heaven's sake, sir, do not turn me away; listen to what I have to tell you, and if it be not possible for you to do me justice, at least you will not one day have to reproach yourself before God for having made yourself the accomplice of a bad action."

Van Systens stamped his foot with impatience; it was the second time that Rosa interrupted him in the midst of a composition which stimulated his vanity, both as a burgomaster and as President of the Horticultural Society.

"But my report!" he cried, -- "my report on the black tulip!"

"Mynheer van Systens," Rosa continued, with the firmness of innocence and truth, "your report on the black tulip will, if you don't hear me, be based on crime or on falsehood. I implore you, sir, let this Master Boxtel, whom I assert to be Master Jacob, be brought here before you and me, and I swear that I will leave him in undisturbed possession of the tulip if I do not recognise the flower and its holder."

"Well, I declare, here is a proposal," said Van Systens.

"What do you mean?"

"I ask you what can be proved by your recognising them?"

"After all," said Rosa, in her despair, "you are an honest man, sir; how would you feel if one day you found out that you had given the prize to a man for something which he not only had not produced, but which he had even stolen?"

Rosa's speech seemed to have brought a certain conviction into the heart of Van Systens, and he was going to answer her in a gentler tone, when at once a great noise was heard in the street, and loud cheers shook the house.

"What is this?" cried the burgomaster; "what is this? Is it possible? have I heard aright?"

And he rushed towards his anteroom, without any longer heeding Rosa, whom he left in his cabinet.

Scarcely had he reached his anteroom when he cried out aloud on seeing his staircase invaded, up to the very landing-place, by the multitude, which was accompanying, or rather following, a young man, simply clad in a violet-coloured velvet, embroidered with silver; who, with a certain aristocratic slowness, ascended the white stone steps of the house.
