“How much do you know?” he asked at last, without raising his head.

“I saw you together last night.”

“Does anyone else beside your friend know?”

“I have spoken to no one.”

The Duke took a pen in his quivering fingers and opened his check-book.

“I shall be as good as my word, Mr. Holmes. I am about to write your check, however unwelcome the information which you have gained may be to me. When the offer was first made, I little thought the turn which events might take. But you and your friend are men of discretion, Mr. Holmes?”

“I hardly understand your Grace.”

“I must put it plainly, Mr. Holmes. If only you two know of this incident, there is no reason why it should go any farther. I think twelve thousand pounds is the sum that I owe you, is it not?”

But Holmes smiled and shook his head.

“I fear, your Grace, that matters can hardly be arranged so easily. There is the death of this schoolmaster to be accounted for.”

“But James knew nothing of that. You cannot hold him responsible for that. It was the work of this brutal ruffian whom he had the misfortune to employ.”

“I must take the view, your Grace, that when a man embarks upon a crime, crime he is morally guilty of any other crime which may spring from it.”

“Morally, Mr. Holmes. No doubt you are right. But surely not in the eyes of the law. A man cannot be condemned for a murder at which he was not present, and which he loathes and abhors as much as you do. The instant that he heard of it he made a complete confession to me, so filled was he with horror and remorse. He lost not an hour in breaking entirely with the murderer. Oh, Mr. Holmes, you must save him — you must save him! I tell you that you must save him!” The Duke had dropped the last attempt at self-command, and was pacing the room with a convulsed face and with his clenched hands raving in the air. At last he mastered himself and sat down once more at his desk. “I appreciate your conduct in coming here before you spoke to anyone else,” said he. “At least, we may take counsel how far we can minimize this hideous scandal.”

“Exactly,” said Holmes. “I think, your Grace, that this can only be done by absolute frankness between us. I am disposed to help your Grace to the best of my ability, but, in order to do so, I must understand to the last detail how the matter stands. I realize that your words applied to Mr. James Wilder, and that he is not the murderer.”

“No, the murderer has escaped.”

Sherlock Holmes smiled demurely.

“Your Grace can hardly have heard of any small reputation which I possess, or you would not imagine that it is so easy to escape me. Mr. Reuben Hayes was arrested at Chesterfield, on my information, at eleven o’clock last night. I had a telegram from the head of the local police before I left the school this morning.”

The Duke leaned back in his chair and stared with amazement at my friend.

"How does your Highness wish me to be dressed?" faltered Rosa.

"Take the costume of a Frisian bride." said William; "it will suit you very well indeed."

Haarlem, whither, three days ago, we conducted our gentle reader, and whither we request him to follow us once more in the footsteps of the prisoner, is a pleasant city, which justly prides itself on being one of the most shady in all the Netherlands.

While other towns boast of the magnificence of their arsenals and dock-yards, and the splendour of their shops and markets, Haarlem's claims to fame rest upon her superiority to all other provincial cities in the number and beauty of her spreading elms, graceful poplars, and, more than all, upon her pleasant walks, shaded by the lovely arches of magnificent oaks, lindens, and chestnuts.

Haarlem, -- just as her neighbour, Leyden, became the centre of science, and her queen, Amsterdam, that of commerce, -- Haarlem preferred to be the agricultural, or, more strictly speaking, the horticultural metropolis.

In fact, girt about as she was, breezy and exposed to the sun's hot rays, she seemed to offer to gardeners so many more guarantees of success than other places, with their heavy sea air, and their scorching heat.

On this account all the serene souls who loved the earth and its fruits had gradually gathered together at Haarlem, just as all the nervous, uneasy spirits, whose ambition was for travel and commerce, had settled in Rotterdam and Amsterdam, and all the politicians and selfish worldlings at the Hague.

We have observed that Leyden overflowed with scholars. In like manner Haarlem was devoted to the gentle pursuits of peace, -- to music and painting, orchards and avenues, groves and parks. Haarlem went wild about flowers, and tulips received their full share of worship.

Haarlem offered prizes for tulip-growing; and this fact brings us in the most natural manner to that celebration which the city intended to hold on May 15th, 1673 in honour of the great black tulip, immaculate and perfect, which should gain for its discoverer one hundred thousand guilders!

Haarlem, having placed on exhibition its favourite, having advertised its love of flowers in general and of tulips in particular, at a period when the souls of men were filled with war and sedition, -- Haarlem, having enjoyed the exquisite pleasure of admiring the very purest ideal of tulips in full bloom, -- Haarlem, this tiny town, full of trees and of sunshine, of light and shade, had determined that the ceremony of bestowing the prize should be a fete which should live for ever in the memory of men.

So much the more reason was there, too, in her determination, in that Holland is the home of fetes; never did sluggish natures manifest more eager energy of the singing and dancing sort than those of the good republicans of the Seven Provinces when amusement was the order of the day.

Study the pictures of the two Teniers.

It is certain that sluggish folk are of all men the most earnest in tiring themselves, not when they are at work, but at play.
