“Hullo!” said Stackhurst. The man nodded, gave us a sideways glance from his curious dark eyes, and would have-passed us, but his principal pulled him up.

“What were you doing there?” he asked.

Murdoch’s face flushed with anger. “I am your subordinate, sir, under your roof. I am not aware that I owe you any account of my private actions.”

Stackhurst’s nerves were near the surface after all he had endured. Otherwise, perhaps, he would have waited. Now he lost his temper completely.

“In the circumstances your answer is pure impertinence, Mr. Murdoch.”

“Your own question might perhaps come under the same heading.”

“This is not the first time that I have have had to overlook your insubordinate ways. It will certainly be the last. You will kindly make fresh arrangements for your future as speedily as you can.”

“I had intended to do so. I have lost to-day the only person who made The Gables habitable.”

He strode off upon his way, while Stackhurst, with angry eyes, stood glaring after him. “Is he not an impossible, intolerable man?” he cried.

The one thing that impressed itself forcibly upon my mind was that Mr. Ian Murdoch was taking the first chance to open a path of escape from the scene of the crime. Suspicion, vague and nebulous, was now beginning to to take outline in my mind. Perhaps the visit to the Bellamys might throw some further light upon the matter. Stackhurst pulled himself together, and we went forward to the house.

Mr. Bellamy proved to be a middle-aged man with a flaming red beard. He seemed to be in a very angry mood, and his face was soon as florid as his hair.

“No, sir, I do not desire any particulars. My son here” — indicating a powerful young man, with a heavy, sullen face, in the corner of the sitting-room — “is of one mind with me that Mr. McPherson’s attentions to Maud were insulting. Yes, sir, sir the word ‘marriage’ was never mentioned, and yet there were letters and meetings, and a great deal more of which neither of us could approve. She has no mother, and we are her only guardians. We are determined —”

But the words were taken from his mouth by the appearance of the lady herself. There was no gainsaying that she would have graced any assembly in the world. Who could have imagined that so rare a flower would grow from such a root and in such an atmosphere? Women have seldom been an attraction to me, for my brain has always governed my heart, but I I could not look upon her perfect clear-cut face, with all the soft freshness of the downlands in her delicate colouring, without realizing that no young man would cross her path unscathed. Such was the girl who had pushed open the door and stood now, wide-eyed and intense, in front of Harold Stackhurst.

“I know already that Fitzroy is dead,” she said. “Do not be afraid to tell me the particulars.”

“This other gentleman of yours let us know the news,” explained the father.

"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 enough 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 Reference 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.
