The threatened interrogation never happened; and one evening it was announced that our party of seven was to return to Afion-kara-Hissar. From every point of view it would be advisable to remain in Constantinople. I believed it to be the only Turkish town in which one might arrange a successful escape, and I knew that it contained civilians who were either British themselves or willing to help British prisoners. Moreover, it offered infinite possibilities in the way of distraction, which were always attainable through _baksheesh_, that lowest common denominator of the Turkish Empire. And if the long-promised exchange of sick prisoners took place Constantinople was obviously the place where strings must be pulled if one wanted to be sent home on the strength of some feigned weakness. There were at Psamatia two officers who had been told that they would be among the first batch of prisoners to leave the country. One of them, Flight-Lieutenant F., claimed to be suffering from some form of tuberculosis difficult of definition and detection but strongly supported by influential friends. The other was Father M., a Roman Catholic padre who was among the captured garrison of Kut-el-Amara. It was evident that thirty months of captivity had seriously affected his well-being, mental and physical. In any case, as a non-combatant well over military age, the white-haired priest should most certainly have been allowed to leave Turkey. Meanwhile, he was well loved by all at Psamatia, even by the guards, who knew him as "Pappas Effendi." Whenever he passed down the street children from among the Catholic Christians who lived near the prison-house would stand in his way, and demand a blessing. Unfortunately there was in the camp library no medical text-book to tell how a prisoner might feign nervous disorders. I had to be content with coaching from Pappas Effendi, and with practising before the mirror a doleful look, tempered by a variety of twitchings. Then I visited the camp doctor. Ever since my aeroplane smash, I complained with mournful insistence, I had suffered terribly from _vertige_, from periods of utter forgetfulness, from maddening melancholia, and from nervous outbreaks. Above all from _vertige_. Fortunately the doctor, like most Turkish medical men, was both ignorant and lazy. His day's work was to sit in an office for two hours, always smoking a cigarette through an absurdly long holder, and having listened to the translated statements of would-be patients, either to send them away with a pill or to write out a form whereby they could be examined at a hospital. A wound or an injury he might have treated by pill; but it was plain that the very suggestion of mental trouble stumped him. He could not withstand the word _vertige_, and after a second repetition of it I had no difficulty in procuring a chit ordering me to be dealt with by a hospital doctor.
