How long I stood for this infernal proceeding I do not know. But I recall a realization that I had lost grip on my thoughts and seemed to be floating off into a misty nowhere of unconsciousness. I struggled frantically to regain control of myself; and, for what seemed an eternity, I fought with a horrible nightmare unable to move a muscle or even close my eyelids to shut out that sickening sequence of creeping shadows. Then I saw the doctor's hand reaching slowly toward my face. It seemed to sway in its stealthy movement like the head of a serpent charming a bird, but in my helpless horror I could not ward it off.
At last the snaky fingers touched my eyelids as if to close them, and that touch, light though it was, served to snap the taut film of my helpless brain and I gave a blood-curdling yell and jumped up, knocking over the devilish apparatus and nearly upsetting the doctor.
"Calm yourself," said Boehm, as he attempted to push me again toward the couch. "There is nothing wrong, and you must surrender to the psychic equilibrator so that I can proceed with the examination."
"Examination be damned," I shouted fiercely; "you were trying to hypnotize me with that infernal machine."
Boehm did not reply but calmly proceeded to pick up the apparatus and restore it to its place in the corner, while I paced angrily about the room. He then seated himself and addressed me as I stood against the wall glaring at him. "You are labouring under hallucinations," he said. "I fear your case is even worse than I thought. But calm yourself. I shall attempt no further examination today."
I resumed a seat but refused to look at him. He did not talk further of my supposed mental state, but proceeded to entertain me with gossip of the Royal Level, and later discussed the novels in the bookcase.
It was difficult to keep up an open war with so charming a conversationalist, but I was thoroughly on my guard. I could now readily see through the whole fraud of my imputed mental derangement. I knew my mind was sound as a schoolboy's, and that this pretence of examination and treatment was only a blind. Evidently the Chemical Staff had failed to work the formulas I had given them and this psychic manipulator had been sent in here to filch the true formulas from my brain with his devilish art. I knew nothing of what progress the Germans might have made with hypnotism, but unless they had gone further than had the outer world, now that I was on my guard, I believed myself to be safe.
But there was yet one danger. I might be trapped in my sleep by an induced somnambulistic conversation. Happily I was fairly well posted on such things and believed that I could guard against that also. But the fear of the thing made me so nervous that I did not sleep all of the following night.
The doctor, evidently a keen observer, must have detected that fact from the sound of my breathing, for the lights were turned out and we slept in the pitchy blackness that only a windowless room can create.
"You did not sleep well," he remarked, as we breakfasted.
