"You might say good-night to Christopher when you go upstairs," Aymer said casually a little later, and his father nodded assent, by no means deceived by the indifferent tone. Both Aymer and Christopher slept the better for his ministrations that night. CHAPTER VII At the end of February the elder Astons returned to town and Marden Court was no longer mere vague locality to Christopher, but the "home" of those he loved, the centre piece of their lives, and he had a share in it himself. Still he was very happy to find himself back at Aston House. Its many deserted rooms, the long, silent corridors and its strange spacious emptiness lent themselves to his robust imagination more easily than the living friendly warmth of the old house, brimful of actualities. He re-explored every corner of house and garden in the first days of return, interviewed the staff collectively and individually, from Warren the butler, to the new scullery boy. He rearranged his books and hunted up half-forgotten treasures, slid down the shiny banisters fifty times a day and dispelled the silent lurking shadows with a merry whistle and a laugh that woke an echo in quiet rooms. But he regretted Patricia. It would have been very pleasant to take his turn at showing her round--Patricia had only been in London once,--and there would have been plenty to show her. Lessons, however, recommenced almost at once and Christopher was left with little time for regrets. Life fell back into its old grooves with the solitary difference that those grooves seemed deeper worn and more familiar than he had imagined. The months no longer only presented possible problems; he could consult his memory as to what had previously been at such a time or in like conditions. He was also given much greater liberty now and encouraged to go out by himself, and to do errands for Mr. Aston or Aymer. It was a proud day for him when Aymer first sent him to The House with a letter for Mr. Aston, who was acting secretary on a Committee at the time. Christopher had had to wait and had sat outside a Committee room door and watched men go to and fro, men whose faces were dimly familiar to a student of illustrated papers, and men who were strange, but all men doing something in return for the good things the world had given them. Such at least was Christopher's innocent belief. Aymer did not disillusion him. He used to recount his small adventures to Caesar in the evenings and was encouraged to form his own conclusions from what he had noticed and to confirm existing ideas from actual life. Such conclusions and ideas were naturally often childish and illogical, but Caesar never appeared to find them laughable and would give careful and illuminating consideration to the most chaotic theories.
