In chapter 48 of Nicholas Nickleby, Dickens expresses quite strong views on writers of plays adapted from books:
'Shot beyond him [Shakespear], I mean,' resumed Nicholas, 'in quite another respect, for, whereas he brought within the magic circle of his genius, traditions peculiarly adapted for his purpose, and turned familiar things into constellations which should enlighten the world for ages, you drag within the magic circle of your dulness, subjects not at all adapted to the purposes of the stage, and debase as he exalted. For instance, you take the uncompleted books of living authors, fresh from their hands, wet from the press, cut, hack, and carve them to the powers and capacities of your actors, and the capability of your theatres, finish unfinished works, hastily and crudely vamp up ideas not yet worked out by their original projector, but which have doubtless cost him many thoughtful days and sleepless nights; by a comparison of incidents and dialogue, down to the very last word he may have written a fortnight before, do your utmost to anticipate his plot--all this without his permission, and against his will; and then, to crown the whole proceeding, publish in some mean pamphlet, an unmeaning farrago of garbled extracts from his work, to which your name as author, with the honourable distinction annexed, of having perpetrated a hundred other outrages of the same description. Now, show me the distinction between such pilfering as this, and picking a man's pocket in the street: unless, indeed, it be, that the legislature has a regard for pocket-handkerchiefs, and leaves men's brains, except when they are knocked out by violence, to take care of themselves.'
Considering he himself at one time wrote a play, and the viciousness of the attack, I wondered if Dickens was venting some of his own anger.
In particular, did Dickens have someone who was 'cutting, hacking and carving' his works at the time he was writing Nicholas Nickleby, and was this barb introduced as some revenge upon that person?
