"Well asked, Watson. You would certainly fall down badly if you did not know the value of your own wares. This saucer was got for me by Sir James, and comes, I understand, from the collection of his client. You will not exaggerate if you say that it could hardly be matched in the world."

"I could perhaps suggest that the set should be valued by an expert."

"Excellent, Watson! You scintillate today. Suggest Christie or Sotheby. Your delicacy prevents your putting a price for yourself."

"But if he won't see me?"

"Oh, yes, he will see you. He has the collection mania in its most acute form – and especially on this subject, on which he is an acknowledged authority. Sit down, Watson, and I will dictate the letter. No answer needed. You will merely say that you are coming, and why."

It was an admirable document, short, courteous, and stimulating to the curiosity of the connoisseur. A district messenger was duly dispatched with it. On the same evening, with the precious saucer in my hand and the card of Dr. Hill Barton in my pocket, I set off on my own adventure.

The beautiful house and grounds indicated that Baron Gruner was, as Sir James had said, a man of considerable wealth. A long winding drive, with banks of rare shrubs on either side, opened out into a great graveled square adorned with statues. The place had been built by a South African gold king in the days of the great boom, and the long, low house with the turrets at the corners, though an architectural nightmare, was imposing in its size and solidity. A butler, who would have adorned a bench of bishops, showed me in and handed me over to a plush-clad footman, who ushered me into the Baron's presence.

He was standing at the open front of a great case which stood between the windows and which contained part of his Chinese collection. He turned as I entered with a small brown vase in his hand.

"Pray sit down, Doctor," said he. "I was looking over my own treasures and wondering whether I could really afford to add to them. This little Tang specimen, which dates from the seventh century, would probably interest you. I am sure you never saw finer workmanship or a richer glaze. Have you the Ming saucer with you of which you spoke?"

I carefully unpacked it and handed it to him. He seated himself at his desk, pulled over the lamp, for it was growing dark, and set himself to examine it. As he did so the yellow light beat upon his own features, and I was able to study them at my ease.

He was certainly a remarkably handsome man. His European reputation for beauty was fully deserved. In figure he was not more than of middle size, but was built upon graceful and active lines. His face was swarthy, almost Oriental, with large, dark, languorous eyes which might easily hold an irresistible fascination for women. His hair and mustache were raven black, the latter short, pointed, and carefully waxed. His features were regular and pleasing, save only his straight, thin-lipped mouth. If ever I saw a murderer's mouth it was there – a cruel, hard gash in the face, compressed, inexorable, and terrible. He was ill-advised to train his mustache away from it, for it was Nature's danger-signal, set as a warning to his victims. His voice was engaging and his manners perfect. In age I should have put him at little over thirty, though his record afterwards showed that he was forty-two.

"Very fine – very fine indeed!" he said at last. "And you say you have a set of six to correspond. What puzzles me is that I should not have heard of such magnificent specimens. I only know of one in England to match this, and it is certainly not likely to be in the market. Would it be indiscreet if I were to ask you, Dr. Hill Barton, how you obtained this?"

"Does it really matter?" I asked with as careless an air as I could muster.

"You can see that the piece is genuine, and, as to the value, I am content to take an expert's valuation."

"Very mysterious," said he with a quick, suspicious flash of his dark eyes. "In dealing with objects of such value, one naturally wishes to know all about the transaction. That the piece is genuine is certain. I have no doubts at all about that. But suppose – I am bound to take every possibility into account – that it should prove afterwards that you had no right to sell?"

"I would guarantee you against any claim of the son."

"That, of course, would open up the question as to what your guarantee was worth."

"My bankers would answer that."

"Quite so. And yet the whole transaction strikes me as rather unusual."

"You can do business or not," said I with indifference. "I have given you the first offer as I understood that you were a connoisseur, but I shall have no difficulty in other quarters."

"Who told you I was a connoisseur?"

"I was aware that you had written a book upon the subject."

"Have you read the book?"

"No."

"Dear me, this becomes more and more difficult for me to understand! You are a connoisseur and collector with a very valuable piece in your collection, and yet you have never troubled to consult the one book which would have told you of the real meaning and value of what you held. How do you explain that?"

"I am a very busy man. I am a doctor in practice."

"That is no answer. If a man has a hobby he follows it up, whatever his other pursuits may be. You said in your note that you were a connoisseur."

"So I am."

"Might I ask you a few questions to test you? I am obliged to tell you, Doctor – if you are indeed a doctor – that the incident becomes more and more suspicious. I would ask you what do you know of the Emperor Shomu and how do you associate him with the Shoso-in near Nara? Dear me, does that puzzle you? Tell me a little about the Northern Wei dynasty and its place in the history of ceramics."

I sprang from my chair in simulated anger.

"This is intolerable, sir," said I. "I came here to do you a favor, and not to be examined as if I were a schoolboy. My knowledge on these subjects may be second only to your own, but I certainly shall not answer questions which have been put in so offensive a way."

He looked at me steadily. The languor had gone from his eyes. They suddenly glared. There was a gleam of teeth from between those cruel lips.

"What is the game? You are here as a spy. You are an emissary of Holmes. This is a trick that you are playing upon me. The fellow is dying I hear, so he sends his tools to keep watch upon me. You've made your way in here without leave, and, by God! you may find it harder to get out than to get in."

He had sprung to his feet, and I stepped back, bracing myself for an attack, for the man was beside himself with rage. He may have suspected me from the first; certainly this cross-examination had shown him the truth; but it was clear that I could not hope to deceive him. He dived his hand into a side-drawer and rummaged furiously. Then something struck upon his ear, for he stood listening intently.

"Ah!" he cried. "Ah!" and dashed into the room behind him.

Two steps took me to the open door, and my mind will ever carry a clear picture of the scene within. The window leading out to the garden was wide open. Beside it, looking like some terrible ghost, his head gin with bloody bandages, his face drawn and white, stood Sherlock Holmes. The next instant he was through the gap, and I heard the crash of his body among the laurel bushes outside. With a howl of rage the master of the house rushed after him to the open window.

And then! It was done in an instant, and yet I clearly saw it. An arm – a woman's arm – shot out from among the leaves. At the same instant the Baron uttered a horrible cry – a yell which will always ring in my memory. He clapped his two hands to his face and rushed round the room, beating his head horribly against the walls. Then he fell upon the carpet, rolling and writhing, while scream after scream resounded through the house.
