Seconded.
Personally I would also recommend
League of Extraordinary Gentlemen, if you're interested in re-interpretations of Victorian stories. And no, the original comic is nothing unlike that film by the same name
THAT WAS NEVER MADE.
The problem, however, is that if you think Watchmen is dense with imagery,
League has about one Victorian novel easter egg per panel (it gets better/worse in the supplemental
New Traveller's Almanac which has about one every sentence
).
