"Keep him close by," Field said. "He is just valiantly drunk now, but unless I greatly mistake my man, he will listen to reason shortly. Don't take him far away, as I may want to make use of him presently. I am glad that he arrived on the scene before the motor came up." Again the tense silence fell on the group; once more they had to possess their souls in patience. Field appeared more cheerful and philosophical; the arrest of Bentwood seemed to have taken a heavy weight from his mind. He took out a cigarette and lighted it. Mark turned to Mary. "You are sure that you will not reconsider your decision?" he said. "I wish that I could persuade you not to remain here. It has been quite painful enough for you already, and you can do no good. Why should you witness the final humiliation of it?" Mary looked at the speaker; a grateful sigh came from her lips. "You are more than kind to me," she said. "But I have drunk so deeply of the cup of humiliation that a draught more or less makes no difference. Heaven knows how I have tried to avert this thing, to ward off the danger that I could not see. And yet all this time I knew that sooner or later the blow would fall. Mr. Ventmore, how old do you take me to be?" Mark could not say. It was rather an awkward question. "I see by your silence that you would rather not reply," Mary said. "It means that you would have a delicacy in calling me an old woman. And yet I am barely thirty. When I think what I was three years ago, it seems to me as if ages had passed. Of course, this is all silly talk, but I must talk or go mad." "There is a happier time coming for you," Mark said. "I know that. Once that blow has fallen, I shall regard myself as free of my cares. And now, with that prospect before me, I would avert the calamity if I could. And yet I have done my best and nobody could do more." Silence fell again, for Mark could not think of anything else to say. The silence was broken presently by the clang and snarl of a distant motor car, and Field pitched his cigarette away. He seemed to have become good-humoured all at once. "That is good," he exclaimed. "Our patience has been rewarded at last. Another few minutes and we will go and see what the house has in store for us. There's the other man." The motor pulled up opposite No. 100, and two men got out--followed by a third in clerical costume. The latter seemed to be protesting about something. As he came up the drive Field stepped out, and the two men who had engineered the motor car saluted. "You have done exceedingly well," Field said in a pleased voice. "You will just stay where you are, because you may be wanted. So you have brought the gentleman from Edward Street? I telephoned your chief to make a raid on the place just now." "But this is an outrage," the clerical figure said in a shaky voice. "To take a gentleman from his lodgings in that way is something that even the police----"
