"I suppose your sins are finding you out," he said. "They generally do. Personally, I have no curiosity on the subject at all. And I have not the slightest doubt that your punishment, though pretty severe, was at the same time well deserved. And now, sir, as fate has given me the whip hand of you, have you any reason to urge why I should stay in this house any longer? I take it that you are not quite in a position to place your electric battery at work from this room as you did from the other. If you like to----" Berrington paused, as there was a loud knocking at the door. Sartoris's pale face grew still paler as he listened. Then he forced a smile to his pallid lips. "Don't take any heed," he said eagerly. "Let them go away again under the impression that nobody is at the house. Let them knock all night if they like." But Berrington was already half-way to the door. CHAPTER XXV With the letter to Beatrice safe in her pocket, Mary made her way to the _Royal Palace Hotel_. She had her own idea as to what she was going to do, and that certainly was not to invite Beatrice to go to Wandsworth. For the girl had a difficult and dangerous task before her. Rightly or wrongly, it seemed to her that her place was by the side of the brother who had treated her so badly. Many a good woman before had sacrificed herself to a scoundrel, and many a good woman will do so again. Mary had always clung to the idea that Sartoris might be brought back to the fold again. She knew pretty well how far he had fallen, but she did not quite understand the deep depravity of the man's nature. After all, he was an object to be pitied; after all, he had been the victim of a woman's cruelty, or so Mary thought. But Mary did not know everything; had she done so she would have been forced to leave her brother to his own devices. She came at length to the _Royal Palace Hotel_, and asked for Beatrice. The latter was in her room, she was told, and Mary went up. But Beatrice was not there, her place for the time being occupied by Adeline, the maid. "My mistress is out," the maid explained; "but if you will leave any message I can deliver it. She will not be very long, in any case." Mary hesitated. She had many things to do and no time to waste. It was not altogether imperative that she should see Beatrice just at the moment. She turned the matter over in her mind before she replied to Adeline's suggestion. "I rather wanted to see your mistress," she said. "Perhaps I may make it convenient to return in about half an hour or so. Meanwhile, will you please give her this letter. Will you be very careful to say that Mrs. Richford is to do nothing till she has seen me? I mean that she is not to take any steps in the matter of the letter till I come back. Will you be especially careful about that?"
