"That is very nice and obliging of you," Mayfield said grimly. "I am going to make no effort to undermine your virtue. We do not want the servants to know who you are or what you are doing. There's £5 cash for you if you can manage this. I'm told it is often done. What do you suggest?" As he spoke, Mayfield played thoughtfully with some sovereigns. The big man grinned. "Now you are speaking fair," he said. "If people meet us all right and don't regard us as convicts or bushrangers, why, we can meet other people. The three of us have been in many a good house together. The last time we came down to go over the place to give a proper estimate for electric light. You've only got to look wise and potter about with a foot rule and a notebook, and there you are! We can pretend to be measuring outside when the servants come down in the morning, and I daresay Sir George can arrange for our food to be given us somewhere handy. Bless your life, there's many a way of doing it, if you'll give me the brass for the other two chaps and settle it at once." Mayfield handed over a little pile of sovereigns and the man shuffled off in the direction of the kitchen. Mayfield smiled at the success of his errand. "There," he said; "I fancy that is all right. Only you must tell Sir George exactly what has happened so that there is no confusion in the morning. Sir George is thinking of having the electric light installed. The men are here to take measurements. They will keep the joke to themselves. You ought to be very much obliged to me." But no protestation of gratitude came from Mary's lips. The light of a great scorn was still in her eyes. "Lies and prevarication and deceit," she said. "I seem to have found myself in a very network of falsehood. The poorest girl on the estate is happier than I am. It may be as you say, it may be that we shall escape the tongue of scandal. But what are you going to do--how long is the deception to go on?" "That depends on yourself," Mayfield said coolly. "You can defy me if you like, and take the consequences. But it shall not be said that I have treated you unfairly. That is why I am giving you another night to think the matter over. Now go and tell Sir George what has happened." Mary turned on her heel and left the room without another word. There was a sinister smile on Mayfield's lips as he watched the girl's drooping figure. "The thing will pass as far as she is concerned," he muttered. "And now to tackle Lady Dashwood and have matters out with her." CHAPTER XVIII. A FLAMING SWORD Mary dragged herself as far as the library. Sir George was pacing up and down the room, trying to soothe his nerves with a cigar. "What a time you have been!" he said impatiently. "Why did you not return before, knowing how anxious I should be? Mayfield came for a telegram form, so I presume he has made matters right with you? Did Walters take it?"
