These observations are pertinent to the course of our story, in respect of which the incidents already narrated may be accepted as a kind of prologue. The scene changes to the busy East of this mighty city, the precise locality being a second-hand bookshop in Church Alley. The proprietor of this shop was Mr. Joseph Loveday, Nansie's uncle, and that the reflections upon the shiftings in life's kaleidoscope are not out of place was proved by words which fell from his lips as he sorted a pile of books which he had purchased at auction. "Change, change, change--nothing but change. Some drop out, some remain, and time rolls on. I live, with a likelihood of living for many years; he is dying, with the certainty of death in the course of a few days. So he says in his letter, and in serious affairs he was never given to light talk. Presently he will leave the world behind him. What matters?" The question, addressed with mingled bitterness and mournfulness to himself, aroused him from his reverie. "It does matter," he said. "We are not exactly lumber." He was a man of middle age, a bachelor, and he conducted his business alone, without assistance of any kind, taking down his shutters in the morning and putting them up again at night, arranging the books on his shelves within and on the stall without, and knowing where to lay his hand, almost blindfold, upon any volume which he or a customer required.

Of late he had thought seriously of employing an assistant, but the difficulty was to find one to suit both his business and his peculiarities. In his domestic arrangements he was compelled to call in assistance. He employed a charwoman twice a week, for half a day on each occasion, to clean his place and set it in order; his breakfasts, teas, and suppers he prepared himself with his own hands, and when he did not purchase his dinner at a convenient cook-shop, it was sent in to him by Mrs. Peeper, keeper of a wardrobe-shop in Church Alley. He looked older than he was, and had too early acquired a stoop from poring over books; he had blue eyes, large and shapely hands, and features furrowed with lines of thoughtfulness. When he was not called away to attend an auction or upon other business, he would be seen sitting at his counter, or upon the floor, sorting books and making lists of them, or standing at his door in slippers, wearing a loose dressing-gown and a plain skull-cap, and with a pair of spectacles
