A little-known writer whose surviving work points to a taste for sensational crime and melodrama, he is remembered today chiefly for A Servant of Satan, a vivid tale built around the notorious assassin Prado. His name now lives on more through reprints and digital archives than through a well-documented public biography.

by Louis Berard
Very little firmly documented biographical information about Louis Berard was available in the sources I could confirm. He appears to be an older author whose work has survived mainly through library-style listings and public-domain preservation rather than through modern reference biographies.
The title most clearly linked to him is A Servant of Satan: Romantic Career of Prado the Assassin, a dramatic crime narrative centered on Prado and presented as a dark, sensational account of crime, intrigue, and execution. Because reliable sources provide so little personal detail, it is safest to describe Berard as an obscure author known primarily through this surviving work.
That obscurity gives his profile a certain curiosity: Berard belongs to the large group of once-published writers whose books outlasted the records of their lives. For readers, that can make his work feel like a rediscovered piece of popular historical storytelling from another era.
