author
Best known for Chicago, Satan’s Sanctum, this elusive late-19th-century writer offered a fierce, book-length look at crime, corruption, and public life in Chicago. Very little biographical information appears to survive, which gives the work an extra air of mystery.

by L. O. Curon
L. O. Curon is credited as the author of Chicago, Satan’s Sanctum, published in Chicago in 1899 by C. D. Phillips & Co. The book is now widely available through public-domain archives, and modern catalog and library listings consistently point to that title as Curon’s best-known work.
From the book itself, Curon comes across as a sharp, engaged observer of civic life. Chicago, Satan’s Sanctum is a forceful account of political corruption, police misconduct, and organized vice in turn-of-the-century Chicago, written with the urgency of someone who wanted readers to confront what was happening in the city rather than look away.
Beyond that book, reliable biographical details about Curon are hard to confirm. No clear mainstream reference entry or verified portrait was readily available in the sources reviewed, so the author remains something of a historical shadow known primarily through this single vivid work.
