The express was heavily laden and to it was attached a carriage reserved for the military, who were accompanying the departing Britishers to the frontier. Curiously enough, not one of us knew definitely what had happened. Rumour was busy, but it was inconclusive. The general feeling was that Britain had taken some drastic action which must have serious results, otherwise we should not have been bundled home so hurriedly. We had been travelling some time when I noticed a lady sauntering along the corridor vainly searching for a seat. I was comfortable, but I instantly surrendered my place to assume a standing position in the corridor where I chatted with several fellow-travellers. I may say that slung over my shoulder was a black leather strap carrying a small camera case in the manner frequently affected by tourists. Ever after I have cursed that innocent looking camera case, and certainly when travelling in the future will favour some other means of carrying photographic apparatus. About half-an-hour passed in this way. Then I observed a young German ambling along the corridor. He came up to us and entered into an idle conversation. One by one the others dropped away from him, not caring to talk with a German. I would have done the same but the strange youth would not let me. He pinned me to the spot with his conversation. At first his questions were extremely innocent, but they soon became somewhat inquisitive and searching, and were purposely directed to discover why I was travelling, where I had been, how long I had been in Germany, and so forth. As the conversation assumed this turn I came to the alert. He was a typical German with all the inexperience of youth, though he doubtless prided himself upon his powers of observation, deduction, and cross-examination by apparently idle questions. But to one and all of his interrogations I gave the retort courteous. His pressing attentions did not escape the notice of my fellow-travellers within earshot. Looking out of the corner of my eye I saw that they did not regard this questioning of myself as being so innocent as it appeared. Many were apparently familiar with German methods of inter-espionage and they extended me silent warning, by sign, frown, and wink. The raw youth disappeared and I forgot all about him. But to my surprise five minutes later I saw him returning along the corridor accompanied by a military official whom he had evidently brought from the military carriage attached to the train. They came straight up to me. The youth pointing directly at me remarked, "Here he is. See! There's the camera on his back!" The officer looked at the strap and turning me round caught sight of the camera case. He nodded in acquiescence. "And I saw him using it," went on the youth triumphantly. "He has been taking photographs of the bridges and sentries along the line!"
