“There was something shocking about the man, Mr. Holmes. It wasn’t merely that ghastly face glimmering as white as cheese in the darkness. It was more subtle than that — something slinking, something furtive, something guilty — something very unlike the frank, manly lad that I had known. It left a feeling of horror in my mind.

“But when a man has been soldiering for a year or two with brother Boer as a playmate, he keeps his nerve and acts quickly. Godfrey had hardly vanished before I was at the window. There was an awkward catch, and I was some little time before I could throw it up. Then I nipped through and ran down the garden path in the direction that I thought he might have taken.

“It was a long path and the light was not very good, but it seemed to me something was moving ahead of me. I ran on and called his name, but it was no use. When I got to the end of the path there were several others branching in different directions to various outhouses. I stood hesitating, and as I did so I heard distinctly the sound of a closing door. It was not behind me in the house, but ahead of me, somewhere in the darkness. That was enough, Mr. Holmes, to assure me that what I I had seen was not a vision. Godfrey had run away from me, and he had shut a door behind him. Of that I was certain.

“There was nothing more I could do, and I spent an uneasy night turning the matter over in my mind and trying to find some theory which would cover the facts. Next day I found the colonel rather more conciliatory, and as his wife remarked that there were some places of interest in the neighbourhood, it gave me an opening to ask whether my presence for one more night would incommode them. A somewhat grudging acquiescence from the old man gave me a clear day in which to make my observations. I was already perfectly convinced that Godfrey was in hiding somewhere near, but where and why remained to be solved.

“The house was so large and so rambling that a regiment might be hid away in it and no one the wiser. If the secret lay there it was difficult for me to penetrate it. But the door which I had heard close was certainly not in the house. I must explore the garden and see what I could find. There was no difficulty in the way, for the old people were busy in their own fashion and left me to my own devices.

“There were several small outhouses, but at the end of the garden there was a detached building of some size — large enough for a gardener’s or a gamekeeper‘s residence. Could this be the place whence the sound of that shutting door had come? I approached it in a careless fashion as though I were strolling aimlessly round the grounds. As I did so, a small, brisk, bearded man in a black coat and bowler hat — not at all the gardener type — came out of the door. To my surprise, he locked it after him and put the key in his pocket. Then he looked at me with some surprise on his face.

“ ‘Are you a visitor here?’ he asked.

“I explained that I was and that I was a friend of Godfrey’s.

"Exactly!" 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 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.
