In his tracking out of the claim to its complete establishment, Mr Pancks had shown a sagacity that nothing could baffle, and a patience and secrecy that nothing could tire. 'I little thought, sir,' said Pancks, 'when you and I crossed Smithfield that night, and I told you what sort of a Collector I was, that this would come of it. I little thought, sir, when I told you you were not of the Clennams of Cornwall, that I was ever going to tell you who were of the Dorrits of Dorsetshire.' He then went on to detail. How, having that name recorded in his note-book, he was first attracted by the name alone. How, having often found two exactly similar names, even belonging to the same place, to involve no traceable consanguinity, near or distant, he did not at first give much heed to this, except in the way of speculation as to what a surprising change would be made in the condition of a little seamstress, if she could be shown to have any interest in so large a property. How he rather supposed himself to have pursued the idea into its next degree, because there was something uncommon in the quiet little seamstress, which pleased him and provoked his curiosity. How he had felt his way inch by inch, and 'Moled it out, sir' (that was Mr Pancks's expression), grain by grain. How, in the beginning of the labour described by this new verb, and to render which the more expressive Mr Pancks shut his eyes in pronouncing it and shook his hair over them, he had alternated from sudden lights and hopes to sudden darkness and no hopes, and back again, and back again. How he had made acquaintances in the Prison, expressly that he might come and go there as all other comers and goers did; and how his first ray of light was unconsciously given him by Mr Dorrit himself and by his son; to both of whom he easily became known; with both of whom he talked much, casually ('but always Moleing you'll observe,' said Mr Pancks): and from whom he derived, without being at all suspected, two or three little points of family history which, as he began to hold clues of his own, suggested others. How it had at length become plain to Mr Pancks that he had made a real discovery of the heir-at-law to a great fortune, and that his discovery had but to be ripened to legal fulness and perfection. How he had, thereupon, sworn his landlord, Mr Rugg, to secrecy in a solemn manner, and taken him into Moleing partnership. How they had employed John Chivery as their sole clerk and agent, seeing to whom he was devoted. And how, until the present hour, when authorities mighty in the Bank and learned in the law declared their successful labours ended, they had confided in no other human being.

'So if the whole thing had broken down, sir,' concluded Pancks, 'at the very last, say the day before the other day when I showed you our papers in the Prison yard, or say that very day, nobody but ourselves would have been cruelly disappointed, or a penny the worse.'

Clennam, who had been almost incessantly shaking hands with him throughout the narrative, was reminded by this to say, in an amazement which even the preparation he had had for the main disclosure smoothed down, 'My dear Mr Pancks, this must have cost you a great sum of money.'

'Pretty well, sir,' said the triumphant Pancks. 'No trifle, though we did it as cheap as it could be done. And the outlay was a difficulty, let me tell you.'

'A difficulty!' repeated Clennam. 'But the difficulties you have so wonderfully conquered in the whole business!' shaking his hand again.

'I'll tell you how I did it,' said the delighted Pancks, putting his hair into a condition as elevated as himself. 'First, I spent all I had of my own. That wasn't much.'

'I am sorry for it,' said Clennam: 'not that it matters now, though. Then, what did you do?'

'Then,' answered Pancks, 'I borrowed a sum of my proprietor.'

'Of Mr Casby?' said Clennam. 'He's a fine old fellow.'

'Noble old boy; an't he?' said Mr Pancks, entering on a series of the dryest snorts. 'Generous old buck. Confiding old boy. Philanthropic old buck. Benevolent old boy! Twenty per cent. I engaged to pay him, sir. But we never do business for less at our shop.'

Arthur felt an awkward consciousness of having, in his exultant condition, been a little premature.

'I said to that boiling-over old Christian,' Mr Pancks pursued, appearing greatly to relish this descriptive epithet, 'that I had got a little project on hand; a hopeful one; I told him a hopeful one; which wanted a certain small capital. I proposed to him to lend me the money on my note. Which he did, at twenty; sticking the twenty on in a business-like way, and putting it into the note, to look like a part of the principal. If I had broken down after that, I should have been his grubber for the next seven years at half wages and double grind. But he's a perfect Patriarch; and it would do a man good to serve him on such terms--on any terms.'

Arthur for his life could not have said with confidence whether Pancks really thought so or not.
