A valuable find
You run across a stack of urban maps. A depiction of Manhattan in 1812, just as New York had started to grow into a proper city. Several detailed charts from the Haussmann plan. Street layouts for Vienna, for Buenos Aires, for Prague.
And there, nestled innocently at the bottom – a comprehensive chart of London's sewers. Updated for 1899 – with marks in red ink detailing intrusions such as the subterranean roots of the Bazaar and where the city's old bowels met with the remains of previous Fallen Cities.
You succeeded in a Watchful challenge! (Simple challenges mean you don't learn so much.) Watchful Watchful has not changed from 230 because it's higher than 230. Puzzling Map You've gained 1 x Puzzling Map (new total 40).
