Towcester is reckoned to appear in Dickens's Pickwick Papers, as the venue of a wondrously and riotously corrupt Parliamentary election (humorous / slapstick, rather than bitter, satire) -- the town being thinly disguised there, under the name of "Eatanswill" (idea of venal candidates plying the voters with food and booze, in the hope of influencing the way they'll vote). Another settlement used recognisably by Dickens -- this one less radically renamed -- is Blundeston, Suffolk (near Lowestoft). Features in David Copperfield, as the hero's birthplace and childhood dwelling-place: name slightly altered to "Blunde[r]stone".
