"I wish to make your acquaintance, and to inquire about milk, butter, and eggs," he said pleasantly. "Mr. Walker suggested that you might be willing to attend to household matters, and that would take a burden off my mind." "We'll be pleased to do it, and reasonable, too, sir," said Mrs. Jackson promptly. "Very well. Come and see me in the morning. Meanwhile, can you arrange for a quart of milk, a pound of butter, and a few eggs to be sent in immediately?" "Oh, yes, sir," said both together, and the expression of relief in the one face was mirrored in the other. "You'll be wanting something cooked now, sir?" went on the older woman, with a new cheerfulness of tone, and Armathwaite would have been a far less capable student of human nature than he was had he failed to see that a much desired entry to the house was now regarded as an assured thing. Suddenly he made up his mind to solve the enigma, whatever it might be, since the theory of a spare bed being in request did not seem to fit the case. "No," he said carelessly, treating the proposal as of slight import, one way or the other. "I wish to be alone this evening. But you can come in early to-morrow. Isn't there a spare key?" "Yes, sir," broke in the girl, for her mother was utterly nonplussed again. "It's on the bunch with the others." He produced the keys from his pocket, and saw that there were two alike. "One of these?" he inquired, meeting the girl's eyes in a steady glance. Then he was sure of his ground. She was so excited that she could hardly answer. He gave her the key, ascertained that she would bring the milk and the rest in a few minutes, and left the two women staring after him. Betty was as good as her word. She made no attempt to prolong her stay, but deposited her purchases on the hall-table, and promised that she or her mother would come about seven in the morning. "Will you need to be called, sir?" she inquired, as an afterthought. "Well, yes. I'm a sound sleeper," he assured her gravely. The statement was true, but it required qualification. A man who had slept many a night under conditions that demanded instant wakefulness if any sinister sound threatened his very existence, did not rank in the class of sound sleepers known to quiet Elmdale. Thereafter he cooked a meal of eggs and bacon, tea and toast, smoked, rambled in the garden, read, thought a good deal, and went to bed.
