The mention of Mr Casby again revived in Clennam's memory the smouldering embers of curiosity and interest which Mrs Flintwinch had fanned on the night of his arrival. Flora Casby had been the beloved of his boyhood; and Flora was the daughter and only child of wooden-headed old Christopher (so he was still occasionally spoken of by some irreverent spirits who had had dealings with him, and in whom familiarity had bred its proverbial result perhaps), who was reputed to be rich in weekly tenants, and to get a good quantity of blood out of the stones of several unpromising courts and alleys.

After some days of inquiry and research, Arthur Clennam became convinced that the case of the Father of the Marshalsea was indeed a hopeless one, and sorrowfully resigned the idea of helping him to freedom again. He had no hopeful inquiry to make at present, concerning Little Dorrit either; but he argued with himself that it might--for anything he knew--it might be serviceable to the poor child, if he renewed this acquaintance. It is hardly necessary to add that beyond all doubt he would have presented himself at Mr Casby's door, if there had been no Little Dorrit in existence; for we all know how we all deceive ourselves--that is to say, how people in general, our profounder selves excepted, deceive themselves--as to motives of action.

With a comfortable impression upon him, and quite an honest one in its way, that he was still patronising Little Dorrit in doing what had no reference to her, he found himself one afternoon at the corner of Mr Casby's street. Mr Casby lived in a street in the Gray's Inn Road, which had set off from that thoroughfare with the intention of running at one heat down into the valley, and up again to the top of Pentonville Hill; but which had run itself out of breath in twenty yards, and had stood still ever since. There is no such place in that part now; but it remained there for many years, looking with a baulked countenance at the wilderness patched with unfruitful gardens and pimpled with eruptive summerhouses, that it had meant to run over in no time.

'The house,' thought Clennam, as he crossed to the door, 'is as little changed as my mother's, and looks almost as gloomy. But the likeness ends outside. I know its staid repose within. The smell of its jars of old rose-leaves and lavender seems to come upon me even here.'
