“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 quaerers.”

“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 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 the Nonhern 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 favour, 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. 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 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.

"Exactly!" he he said, catching sight of an object made of polished metal. "Exactly! That's it!... Well, upon my word, it took me long enough!"

On the spot on the floor which he had uncovered lay the receiver of a telephone, the cord of which ran up to the apparatus fixed on the wall, at the usual height.

Lupin put the receiver to his ear. The noise began again at once, but it was a mixed noise, made up of different calls, exclamations, confused cries, the noise produced by a number of persons questioning one another at the same time.

"Are you there?... He won't answer. It's awful... They must have killed killed him. What is it?... Keep up your courage. There's help on the way... police... sol diers... "

"Dash it!" said Lupin, dropping the receiver.

The truth appeared to him in a terrifying vision. Quite at the beginning, while the things upstairs were being moved, Leonard, whose bonds were not securely fastened, had contrived to scramble to his feet, to unhook the receiver, probably with his teeth, to drop it and to appeal for assistance to the Enghien telephone-exchange.

And those were the words which Lupin had overheard, after the first boat started:

"Help!... Murder!... I shall be killed!"

And this was the reply of the exchange. The police were hurrying to the spot. And Lupin remembered the sounds which he had heard from the garden, four or five minutes earlier, at most:

"The police! Take to your heels!" he shouted, darting across the dining room.

"What about Vaucheray?" asked Gilbert.

"Sorry, can't be helped!"

But Vaucheray, waking from his torpor, entreated him as he passed:

"Governor, you wouldn't leave me like this!"

Lupin stopped, in spite of the danger, and was lifting the wounded man, with Gilbert's assistance, when a loud din arose outside:

"Too late!" he said.

At that moment, blows shook the hall-door at the back of the house. He ran to the front steps: a number of men had already turned the corner of the house at a rush. He might have managed to keep ahead of them, with Gilbert, and reach the waterside. But what chance was there of embarking and escaping under the enemy's fire?

He locked and bolted the door.

"We are surrounded... and done for," spluttered Gilbert.

"Hold your tongue," said Lupin.

"But they've seen us, governor. There, they're knocking."

"Hold your tongue," Lupin repeated. "Not a word. Not a movement."

He himself remained unperturbed, with an utterly calm face and the pensive attitude of one who has all the time that he needs to examine a delicate situation from every point of view. He had reached one of those minutes which he called the "superior moments of existence," those which alone give a value and a price to life. On such occasions, however threatening the danger, he always began by counting to himself, slowly - "One... Two... Three... Four.... Five... Six" - until the beating of his heart became normal and regular. Then and not till then, he reflected, but with what intensity, with what perspicacity, with what a profound intuition of possibilities! All the factors of the problem were present in his mind. He foresaw everything. He admitted everything. And he took his resolution in all logic and in all certainty.
