"I walked back to my seat, outwardly calm, but inwardly a prey to the most dreadful emotions. What could I do? Nothing. On arriving at my destination the fellow also alighted, and as I drove home I felt he was still following me. After that, knowing that I was being shadowed, I had not a moment's peace. I dared not go beyond the gate. I dared not roam around the garden. I hardly knew what I feared, for of course they could have arrested me as easily in the house as outside. At last, I could bear the strain no longer and sent for Mr. Norman. His presence gave me a wonderful sense of security, and as I did not see my persecutor for several days, I really began to hope that the Rosemere tragedy would always remain a mystery, when, picking up the paper one morning, I read that a wretched Frenchman was suspected of the--the death. Of course, there was nothing else for me to do; I must give myself up. Then, you, Doctor, suggested that it might not be necessary, after all--oh, you gave that advice quite unconsciously. I knew that. But when you told me that the man, Argot, was hopelessly insane, and would in any case spend the rest of his days in a lunatic asylum, I wondered if the sacrifice of my life were indeed demanded. At any rate I felt I must go to New York so as to be on hand in case something unexpected occurred, and to watch developments. You can now understand why I begged you so hard to persuade Mamma to bring me here. When I had at last induced you all to let me come, I went out for a walk and was terribly frightened by a tramp whom I mistook for a detective. On reaching New York, I found there was nothing to be done here, and yet I have felt much more calm than I did in the country. Then, yesterday, I met Mr. Merritt, who told me that Mrs. Atkins was suspected, and had fled from her home in consequence. I might hold my tongue where a poor mad creature was concerned, whom my confession could not benefit, but in this case it was not to be thought of. I had a great many last things to attend to, so I decided not to give myself up till to-day. That is the end of my story."
