author
Best known for Chicago, Satan's Sanctum, this elusive writer left behind a fierce portrait of corruption and vice in turn-of-the-century Chicago. Very little biographical information seems to survive, which gives the work an added air of mystery.

by L. O. Curon
L. O. Curon is a little-documented author best known for Chicago, Satan's Sanctum. Available catalog records and public-domain listings consistently point to that book as Curon's principal surviving work, and Project Gutenberg lists only that title under the author's name.
The book was originally published in Chicago in 1899 and is a harsh, detailed attack on crime, police corruption, and political corruption in the city. Modern editions and library-style listings describe it as a late-19th-century work focused on Chicago's underworld and the civic systems that allowed vice to thrive.
Because reliable biographical sources on Curon are scarce, it is hard to say much with confidence about the person behind the name. What can be said is that the author is remembered today mainly through this one uncompromising work of social criticism and urban exposé.
