“Well, that is not unknown among stepmothers. A posthumous jealousy, we will say. Is the lady jealous by nature?”

“Yes, she is very jealous — jealous with all the strength of her fiery tropical love.”

“But the boy — he is fifteen, I understand, and probably very developed in mind, since his body has been circumscribed in action. Did he give you no explanation of these assaults?”

“No, he declared there was no reason.”

“Were they good friends at other times?”

“No, there was never any love between them.”

“Yet you say he is affectionate?”

“Never in the world could there be so devoted a son. My life is his life. He is absorbed in what I say or do.”

Once again Holmes made a note. For some time he sat lost in thought.

“No doubt you and the boy were great comrades before this second marriage. You were thrown very close together, were you not?”

“Very much so.”

“And the boy, having so affectionate a nature, was devoted, no doubt, to the memory of his mother?”

“Most devoted.”

“He would certainly seem to be a most interesting lad. There is one other point about these assaults. Were the strange attacks upon the baby and the assaults upon yow son at the same period?”

“In the first case it was so. It was as if some frenzy had seized seized her, and she had vented her rage upon both. In the second case it was only Jack who suffered. Mrs. Mason had no complaint to make about the baby.”

“That certainly complicates matters.”

“I don’t quite follow you, Mr. Holmes.”

“Possibly not. One forms provisional theories and waits for time or fuller knowledge to explode them. A bad habit, Mr. Ferguson, but human nature is weak. I fear that your old friend here has given an exaggerated view of my scientific methods. However, I will only say at the present stage that your problem does not appear to me to be insoluble, and that you may expect to find us at Victoria at two o’clock.”

It was evening of a dull, foggy November day when, having left our bags at the Chequers, Lamberley, we drove through the Sussex clay of a long winding lane and finally reached the isolated and ancient farmhouse in which Ferguson dwelt. It was a large, straggling building, very old in the centre, very new at the wings with towering Tudor chimneys and a lichen-spotted, high-pitched roof of Horsham slabs. The doorsteps were worn into curves, and the ancient tiles which lined the porch were marked with the rebus of a cheese and a man after the original builder. Within, the ceilings were corrugated with heavy oaken beams, and the uneven floors sagged into sharp curves. An odour of age and decay pervaded the whole crumbling building.

There was one very large central room into which Ferguson led us. Here, in a huge old-fashioned fireplace with an iron screen behind it dated 1670, there blazed and spluttered a splendid log fire.

"Gilbert's calmness is even more impressive, especially when we remember how he broke down at the trial. He retains an unshaken confidence in the omnipotence of Arsene Lupin:

"`The governor shouted to me before everybody not to be afraid, that he was there, that he answered for everything. Well, I'm not afraid. I shall rely on him until the last day, until the last minute, at the very foot of the scaffold. I know the governor! There's no danger with him. He has promised and he will keep his word. If my head were off, he'd come and clap it on my shoulders and firmly! Arsene Lupin allow his chum Gilbert to die? Not he! Excuse my humour!'

"There is a certain touching frankness in all this enthusiasm which is not without a dignity of its own. We shall see if Arsene Lupin deserves the confidence so blindly placed in him."

Lupin was hardly able to finish reading the article for the tears that dimmed his eyes: tears of affection, tears of pity, tears of distress.

No, he did not deserve the confidence of his chum Gilbert. Certainly, he had performed impossibilities; but there are circumstances in which we must perform more than impossibilities, in which we must show ourselves stronger than fate; and, this time, fate had been stronger than he. Ever since the first day and throughout this lamentable adventure, events had gone contrary to his anticipations, contrary to logic itself. Clarisse and he, though pursuing an identical aim, had wasted weeks in fighting each other. Then, at the moment when they were uniting their efforts, a series of ghastly disasters had come one after the other: the kidnapping of little Jacques, Daubrecq's disappearance, his imprisonment in the Lovers' Tower, Lupin's wound, his enforced inactivity, followed by the cunning manceuvres that dragged Clarisse - and Lupin after her - to the south, to Italy. And then, as a crowning catastrophe, when, after prodigies of will-power, after miracles of perseverance, they were entitled to think that the Golden Fleece was won, it all caine to nothing. The list of the Twenty-seven had no more value than the most insignificant scrap of paper.

"The game's up!" said Lupin. "It's an absolute defeat. What if I do revenge myself on Daubrecq, ruin him and destroy him? He is the real victor, once Gilbert is going to die.

He wept anew, not with spite or rage, but with despair. Gilbert was going to die! The lad whom he called his chum, the best of his pals would be gone for ever, in a few hours. He could not save him. He was at the end of his tether. He did not even look round for a last expedient. What was the use?

And his persuasion of his own helplessness was so deep, so definite that he felt no shock of any kind on receiving a telegram from the Masher that said:

"Motor accident. Essential part broken. Long repair. Arrive to-morrow morning."

It was a last proof to show that fate had uttered its decree. He no longer thought of rebelling against the decision.

He looked at Clarisse. She was peacefully sleeping; and this total oblivion, this absence of all consciousness, seemed to him so enviable that, suddenly yielding to a fit of cowardice, he seized the bottle, still half-filled with the sleeping-draught, and drank it down.
