“I was still suspicious of Carton. He was a man whom it was easy enough to frighten, but who, in his fright, would tell so many lies that to sift the truth out from them would be no easy job. I went back to the hotel and waited. By the following evening I judged that he would have received the reply to his cable. I called round at his house and was told that Mr. Carton was away, but would be returning on the morrow. Instantly I became suspicious. In the nick of time I found out that he was in reality sailing for England on the _Kilmorden Castle,_ which left Cape Town in two days’ time. I had just time to journey down and catch the same boat. “I had no intention of alarming Carton by revealing my presence on board. I had done a good deal of acting in my time at Cambridge, and it was comparatively easy for me to transform myself into a grave bearded gentleman of middle age. I avoided Carton carefully on board the boat, keeping to my own cabin as far as possible under the pretence of illness. “I had no difficulty in trailing him when we got to London. He went straight to an hotel and did not go out until the following day. He left the hotel shortly before one o’clock. I was behind him. He went straight to a house-agent in Knightsbridge. There he asked for particulars of houses to let on the river. “I was at the next table also inquiring about houses. Then suddenly in walked Anita Grünberg, Nadina—whatever you like to call her. Superb, insolent, and almost as beautiful as ever. God! how I hated her. There she was, the woman who had ruined my life—and who had also ruined a better life than mine. At that minute I could have put my hands round her neck and squeezed the life out of her inch by inch! Just for a minute or two I saw red. I hardly took in what the agent was saying. It was her voice that I heard next, high and clear, with an exaggerated foreign accent: ‘The Mill House, Marlow. The property of Sir Eustace Pedler. That sounds as though it might suit me. At any rate, I will go and see it.’ “The man wrote her an order, and she walked out again in her regal insolent manner. Not by word or a sign had she recognized Carton, yet I was sure that their meeting there was a preconceived plan. Then I started to jump to conclusions. Not knowing that Sir Eustace was at Cannes, I thought that this house-hunting business was a mere pretext for meeting him in the Mill House. I knew that he had been in South Africa at the time of the robbery, and never having seen him I immediately leaped to the conclusion that he himself was the mysterious ‘Colonel’ of whom I had heard so much.
