“ ‘I thought you might run short in the night-time, sir. It is bitter weather and these rooms are cold.’

“He hesitated before leaving the room, and when I looked round he was standing facing me with a wistful look upon his wrinkled face.

“ ‘Beg your pardon, sir, but I could not help hearing what you said of young Master Godfrey at dinner. You know, sir, that my wife nursed him, and so I may say I am his foster-father. It’s natural we should take an interest. And you say he carried himself well, sir?’

“ ‘There was no braver man in the regiment. He pulled me out once from under the rifles of the Boers, or maybe I should not be here.’

“The old butler rubbed his skinny hands.

“ ‘Yes, sir, yes, that is Master Godfrey all over. He was always courageous. There’s not a tree in the park, sir, that he has not climbed. Nothing would stop him. He was a fine boy — and oh, sir, he was a fine man.’

“I sprang to my feet.

“ ‘Look here!’ I cried. ‘You say he was. You speak as if he were dead. What is all this mystery? What has become of Godfrey Emsworth?’

“I gripped the old man by the shoulder, but he shrank away.

“ ‘I don’t know what you mean, sir. Ask the master about Master Godfrey. He knows. It It is not for me to interfere.’

“He was leaving the room, but I held his arm

“ ‘Listen,’ I said. ‘You are going to answer one question before you leave if I have to hold you all night. Is Godfrey dead?”

“He could not face my eyes. He was like a man hypnotized The answer was dragged from his lips. It was a terrible and unexpected one.

“ ‘I wish to God he was!’ he cried, and, tearing himself free he dashed from the room.

“You will think, Mr. Holmes, that I returned to my chair in no very happy state of mind. The old man’s words seemed to me to bear only one interpretation. Clearly my poor friend had become involved in some criminal or, at the least, disreputable transaction which touched the family honour. That stern old man had sent his son away and hidden him from the world lest some scandal should come to light. Godfrey was a reckless fellow. He was easily influenced by those around him. No doubt he had fallen into bad hands and been misled to his ruin. It was a piteous business, if it was indeed so, but even now it was my duty to hunt him out and see if I could aid him. I was anxiously pondering the matter when I looked up, and there was Godfrey Emsworth standing before me.”

My client had paused as one in deep emotion.

“Pray continue,” I said. “Your problem presents some very unusual features.”

“He was outside the window, Mr. Holmes, with his face pressed against the glass. I have told you that I looked out at the night. When I did so I left the curtains partly open. His figure was framed in this gap. The window came down to the ground and I could see the whole length of it, but it was his face which held my gaze. He was deadly pale — never have I seen a man so white. I reckon ghosts may look like that; but his eyes met mine, and they were the eyes of a living man. He sprang back when he saw that I was looking at him, and he vanished into the darkness.

"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.
