“Quite so,” I replied, “and I would like you to take charge of them for me. If Constantinople court-martials me for spiritualism, I shall ask you to produce these as proof that our experiments were carried on without concealment.”
“Certainly,” said the Colonel, as he locked away the letters in a box. “Now I understand why you can’t give your promise to the Turk. But I want you to give it to me. Will you promise not to attempt communication with anyone in the town by conscious telepathy or any other means?”
“I never have attempted to do so by other means,” I said.
The Colonel’s face grew very stern. “I beg your pardon,” he said severely. “I am informed that the Commandant holds an intercepted letter.”
I nodded.
“It implicates you?”
“Yes, both me and Hill.”
“It refers, does it not, to previous correspondence?”
“It does,” I replied.
“If you have had no communication with outside, will you be good enough to explain how you began this correspondence?”
