"I did not realize that every minute of my activities was being reported to the French by Nguyen Thuong Hien, a man who lived with me and was supported by me. When this Nguyen Thuong Huyen first arrived in Hangchow, he was with Tran Duc Quy; I was quite dubious about him. But later I heard that he was a great-nephew of Main Son (Nguyen Thung Hien), well versed in literary Chinese, the holder of a cử nhân (舉人) degree and familiar with French and quốc ngữ. Owing to his capabilities, I kept him on as my secretary without suspecting that he was an informer for the French.
"At 12 noon on the eleventh day of the Fifth Month, my train from Hangchow arrived at the North Station Shanghai. In order to go quickly to the bank to send the money, I left my luggage at the depository and carried only a small bag with me. As soon as I came out of the train station, I saw a rather luxurious automobile and four Westerners standing by it. I did not realize that they were French, because in Shanghai there was a great mixture of Westerners and there were swarms of foreign visitors. It was quite common for cars to be used to pick up hotel guests. Little did I know that this car was there to kidnap someone! When I had gone a few steps from the station, one of the Westerners came up to me and said in Mandarin: 'This car is very nice; please get in.' I politely refused, saying 'I do not need a car.' Suddenly, one of the Westerners behind the car with a great heave pushed me inside it, the engine accelerated and we were off like a shot. In no time we had already entered the French Concession. The car drew up to the waterfront, where a French warship was docked. I now became a prisoner on this warship."
