"One minute," Beatrice said. "What about Colonel Berrington? What steps have you taken to find him? Are you going to have that house at Wandsworth watched?" Field intimated that he was, though in his opinion it was time wasted. "They will expect something of the kind, you see," he said. "Of course it is a help to me that my presence in the house was not suspected. They may conclude that Berrington was alone in the business, and on the other hand they may not conclude anything of the kind. But, all the same, I am going to have the house carefully watched." Before the day was out the disappearance of Sir Charles's body was obscured by the strange absence of Colonel Berrington. Field would have kept this latter fact concealed as far as possible, but then Berrington's landlady had been his old nurse, and she was not rational in the matter at all. The authorities had promised to do all they could, though the press accused them of being exceedingly lax in the business. As a matter of fact, Field had given his chiefs an inkling of the situation, so that they were really doing their best all the time. A carefully planned watch on the Wandsworth Common house had come to nothing, but the people there had not yet returned; indeed very little could have been done if they had. And Field was turning in another direction. He had to trace the young lady who at one time had been engaged to Carl Sartoris, and he had found it a more difficult business than he had anticipated. It was a delicate business, too, calling for tactful manipulation. A somewhat talkative aunt of the young lady was found at length. She took Field for a lawyer who was seeking the Honorable Violet for her own advantage. "Oh, yes. She has been back from India a long time," Lady Parkstone said. "Violet is a very strange and clever girl. Yes, she has been engaged more than once. But the engagements are always broken off. Violet was always in love with herself. But very clever, as I said before. At one time she bade fair to become quite a famous artist, and she has had stories in the magazines. Her last fad was the stage and that has lasted quite a long time. In fact she is on the stage now." "In London, my lady?" Field asked. "She is not acting under her own name, of course?" "No," Lady Parkstone explained. "She is Miss Adela Vane; at present she is playing at the Comedy Opera House. It is just possible that you know the name." Field knew the name very well. He departed presently well satisfied with the progress that he had made. It was getting quite late by the time he had found out where Miss Vane lodged, but he had time to go back to Scotland Yard again. There, a note from the superintendent of the Wandsworth Police was awaiting him, asking him to go down as soon as possible. The note was vague but it suggested possibilities.
