The Red Spider by Delphi Fabrice / ISBN 9781645250623 / paperback from Snuggly Books. This one comes out in April but I have it in stock now.
"Delphi Fabrice" (the pseudonym of Gaston-Henri-Adhémar Risselin, 1877-1937), the most adamant of Jean Lorrain's disciples, is credited with authoring over one hundred books. None, however, is more bizarre than The Red Spider, here presented in English for the first time in a virtuoso translation by Brian Stableford. The novel, seeking to out-Decadent the most decadent of its predecessors, features Andhré Mordann, an ether-drinking hero seemingly modelled on Lorrain himself, who, in this "black, black, black tale"-a tale of true horror and madness-traverses the boulevards of decline, hobnobbing with drunken prostitutes and homosexual strong-men, licentious merrymakers and waterfront idlers-and, of course, the dancer gloved in imperial crimson.
