In Devil-Worship in France, Waite attempts to discern what is genuine from what is fake in the evidence of 19th century Satanism. To get the answers he spends a great deal of time investigating the French Masonic echelon, debunking a “conspiracy of falsehood” and determining what should be understood by Satanism and what not. Huysmans’ diabolical novel Là-Bas (1891) inspired Waite to write this sceptical analysis.
