Bentwood muttered that it was the last thing he did desire. The door closed with a bang, there was a long silence, broken at last by a feeble cry of pain, a cry something like that of a child who suffers under some drug. Berrington leaped to his feet. As he would have crossed the hall a figure came along--the figure of a woman in a grey dress. It was the grey lady that Beatrice had seen on that fateful evening, the woman who had sat by the side of Mark Ventmore in the Paris theatre. She wrung her hands in silent grief. "Oh, if only there was somebody to help me," she said. "If God would only give to me and send to me a friend at this moment, I would pray----" Berrington stepped out into the light of the hall. "Your prayer has been answered," he said quietly. "I am here to help you, Mary." CHAPTER XVII The grey lady stood there, with her hands pressed to her heart, her great pathetic eyes dilated with a curious fear. It was a long time before she spoke, though it was easy to see that she had penetrated Berrington's disguise. But then, he had spoken in his natural voice, which made all the difference. It seemed to him that the grey lady would have fallen had he not put out his hand and supported her slender frame. "Wait a bit," Berrington whispered. "Don't try to talk yet. You are surprised to see me here, Mary. And yet it is natural enough--you must know that I have been seeking you for years. Why have you carefully avoided me all this time?" A little colour crept into the cheeks of the grey lady. Field had drawn into the background with a feeling that he was not wanted here. Yet he was not pleased at the unexpected contretemps. The detective had mapped out a line for himself, and he desired now to bring it to a successful conclusion. And yet the interruption might not altogether be without its good results. Field had, of course, already heard a great deal about the grey lady, and he did not doubt that the pathetic figure standing there in the doorway was the same person. "You will not forget to be cautious," he whispered. The grey lady started. She had not anticipated that anybody else was there. "Who is that?" she asked. "And how did you get here?" "Well, we got into the house by the pantry window," Berrington explained. He had himself well in hand again by this time. "I am afraid that we must have some kind of an understanding, Mary. Would you mind, Inspector?" Field was understood to say that he had no objection so long as it did not lead to anything rash. He began to wish that he had half a dozen or so of his most trusted men with him. Meanwhile his hands were tied and he could do no more than wait developments. He had naturally a keen desire to know what was going on behind the closed door of the dining-room, but on that score he would have to possess his soul in patience for the time. He had the comfortable assurance that he could bag his birds, one by one, later on.
