Iain Sinclair 
White Chappell, Scarlet Tracings [EPUB ebook] 

A novel about London — its past, its people, its underbelly and its madness."In this extraordinary work Sinclair combines a spiritual inquest into the Whitechapel Ripper murders and the dark side of the late Victorian imagination with a posse of seedy book dealers hot on the trail of obscure rarities of that period. These ruined and ruthless dandies appear and disappear through a phantasmagoria interspersed with occult conjurings and reflections on the nature of fiction and history" GUARDIAN
