One of the more unlikely heroes in English literature is Dickens’s rent collector Pancks, a ‘dry, uncomfortable, dreary Plodder and Grubber’, who shows a ‘sagacity that nothing could baffle, and a patience and secrecy that nothing could tire' to determine that the Dorrits languishing in debtors’ prison are heirs to a fortune that ‘had long lain unknown of, unclaimed and accumulating’. No such sagacity would now be required, at least in America.
