Soon I was on the high-road, and then at the Chalet gates. I heard as in a dream what seemed to be three shrill blasts on a whistle. Then a big car passed me, making for St Anton. For a second I would have hailed it, but it was past me and away. But I had a conviction that my business lay in the house, for I thought Ivery was there, and Ivery was what mattered. I marched up the drive with no sort of plan in my head, only a blind rushing on fate. I remembered dimly that I had still three cartridges in my revolver. The front door stood open and I entered and tiptoed down the passage to the room where I had found the Portuguese Jew. No one hindered me, but it was not for lack of servants. I had the impression that there were people near me in the darkness, and I thought I heard German softly spoken. There was someone ahead of me, perhaps the speaker, for I could hear careful footsteps. It was very dark, but a ray of light came from below the door of the room. Then behind me I heard the hall door clang, and the noise of a key turned in its lock. I had walked straight into a trap and all retreat was cut off. My mind was beginning to work more clearly, though my purpose was still vague. I wanted to get at Ivery and I believed that he was somewhere in front of me. And then I thought of the door which led from the chamber where I had been imprisoned. If I could enter that way I would have the advantage of surprise. I groped on the right-hand side of the passage and found a handle. It opened upon what seemed to be a dining-room, for there was a faint smell of food. Again I had the impression of people near, who for some unknown reason did not molest me. At the far end I found another door, which led to a second room, which I guessed to be adjacent to the library. Beyond it again must lie the passage from the chamber with the rack. The whole place was as quiet as a shell. I had guessed right. I was standing in the passage where I had stood the night before. In front of me was the library, and there was the same chink of light showing. Very softly I turned the handle and opened it a crack.... The first thing that caught my eye was the profile of Ivery. He was looking towards the writing-table, where someone was sitting. CHAPTER XVIII The Underground Railway This is the story which I heard later from Mary.... She was at Milan with the new Anglo-American hospital when she got Blenkiron’s letter. Santa Chiara had always been the place agreed upon, and this message mentioned specifically Santa Chiara, and fixed a date for her presence there. She was a little puzzled by it, for she had not yet had a word from Ivery, to whom she had written twice by the roundabout address in France which Bommaerts had given her. She did not believe that he would come to Italy in the ordinary course of things, and she wondered at Blenkiron’s certainty about the date.
