“Who locked the plans up that night?”

“Mr. Sidney Johnson, the senior clerk.”

“Well, it is surely perfectly clear who took them away. They are actually found upon the person of this junior clerk, Cadogan West. That seems final, does it not?”

“It does, Sherlock, and yet it leaves so much unexplained. In the first place, why did he take them?”

“I presume they were of value?”

“He could have got several thousands for them very easily.”

“Can you suggest any possible motive for taking the papers to London except to sell them?”

“No, I cannot.”

“Then we must take that as our working hypothesis. Young West took the papers. Now this could only be done by having a false key —”

“Several false keys. He had to open the building and the room.”

“He had, then, several false keys. He took the papers to London to sell the secret, intending, no doubt, to have the plans themselves back in the safe next morning before they were missed. While in London on this treasonable mission he met his end.”

“How?”

“We will suppose that he was travelling back to Woolwich when he was killed and thrown out of the compartment.”

“Aldgate, where the body was found, is considerably past the station for London Bridge, which would be his route to Woolwich.”

“Many circumstances could be imagined imagined under which he would pass London Bridge. There was someone in the carriage, for example, with whom he was having an absorbing interview. This interview led to a violent scene in which he lost his life. Possibly he tried to leave the carriage, fell out on the line, and so met his end. The other closed the door. There was a thick fog, and nothing could be seen.”

“No better explanation can be given with our present knowledge; and yet consider, Sherlock, how much you leave untouched. We will suppose, for argument’s sake, that young Cadogan West had determined to convey these papers to London. He would naturally have made an appointment with the foreign agent and kept his evening clear. Instead of that he took two tickets for the theatre, escorted his fiancee halfway there, and then suddenly disappeared.”

“A blind,” said Lestrade, who had sat listening with some impatience to the conversation.

“A very singular one. That is objection No. 1. Objection No. 2: We will suppose that he reaches London and sees the foreign agent. He must bring back the papers before morning or the loss will be discovered. He took away ten. Only seven were in his pocket. What had become of the other three? He certainly would not leave them of his own free will. Then, again, where is the price of his treason? One would have expected to find a large sum of money in his pocket.”

“It seems to me perfectly clear,” said Lestrade. “I have no doubt at all as to what occurred. He took the papers to sell them. He saw the agent. They could not agree as to price. He started home again, but the agent went with him. In the train the agent murdered him, took the more essential papers, and threw his body from the carriage. That would account for everything, would it not?”

Connie was a good deal alone now, fewer people came to Wragby. Clifford no longer wanted them. He had turned against even the cronies. He was queer. He preferred the radio, which he had installed at some expense, with a good deal of success at last. He could sometimes get Madrid or Frankfurt, even there in the uneasy Midlands.

And he would sit alone for hours listening to the loudspeaker bellowing forth. It amazed and stunned Connie. But there he would sit, with a blank entranced expression on his face, like a person losing his mind, and listen, or seem to listen, to the unspeakable thing.

Was he really listening? Or was it a sort of soporific he took, whilst something else worked on underneath in him? Connie did now know. She fled up to her room, or out of doors to the wood. A kind of terror filled her sometimes, a terror of the incipient insanity of the whole civilized species.

But now that Clifford was drifting off to this other weirdness of industrial activity, becoming almost a CREATURE, with a hard, efficient shell of an exterior and a pulpy interior, one of the amazing crabs and lobsters of the modern, industrial and financial world, invertebrates of the crustacean order, with shells of steel, like machines, and inner bodies of soft pulp, Connie herself was really completely stranded.

She was not even free, for Clifford must have her there. He seemed to have a nervous terror that she should leave him. The curious pulpy part of him, the emotional and humanly–individual part, depended on her with terror, like a child, almost like an idiot. She must be there, there at Wragby, a Lady Chatterley, his wife. Otherwise he would be lost like an idiot on a moor.

This amazing dependence Connie realized with a sort of horror. She heard him with his pit managers, with the members of his Board, with young scientists, and she was amazed at his shrewd insight into things, his power, his uncanny material power over what is called practical men. He had become a practical man himself and an amazingly astute and powerful one, a master. Connie attributed it to Mrs Bolton’s influence upon him, just at the crisis in his life.

But this astute and practical man was almost an idiot when left alone to his own emotional life. He worshipped Connie. She was his wife, a higher being, and he worshipped her with a queer, craven idolatry, like a savage, a worship based on enormous fear, and even hate of the power of the idol, the dread idol. All he wanted was for Connie to swear, to swear not to leave him, not to give him away.

‘Clifford,’ she said to him—but this was after she had the key to the hut—‘Would you really like me to have a child one day?’

He looked at her with a furtive apprehension in his rather prominent pale eyes.

‘I shouldn’t mind, if it made no difference between us,’ he said.

‘No difference to what?’ she asked.

‘To you and me; to our love for one another. If it’s going to affect that, then I’m all against it. Why, I might even one day have a child of my own!’
