“I followed my two suspects along Knightsbridge. Nadina went into the Hyde Park Hotel. I quickened my pace and went in also. She walked straight into the restaurant, and I decided that I would not risk her recognizing me at the moment, but would continue to follow Carton. I was in great hopes that he was going to get the diamonds, and that by suddenly appearing and making myself known to him when he least expected it I might startle the truth out of him. I followed him down into the tube station at Hyde Park Corner. He was standing by himself at the end of the platform. There was some girl standing near, but no one else. I decided that I would accost him then and there. You know what happened. In the sudden shock of seeing a man whom he imagined far away in South Africa, he lost his head and stepped back upon the line. He was always a coward. Under the pretext of being a doctor, I managed to search his pockets. There was a wallet with some notes in it and one or two unimportant letters, there was a roll of films⁠—which I must have dropped somewhere later⁠—and there was a piece of paper with an appointment made on it for the 22nd on the Kilmorden Castle . In my haste to get away before anyone detained me, I dropped that also, but fortunately I remembered the figures.
