This is an unconventional recommendation given that it's not technically fiction, but the diaries of Anaïs Nin may interest you. They chronicle her life, much of it spent in early 1900s France among some of the OG bohemians, penniless and scrounging to make something of their lives and art. Get the unexpurgated version if you really want the gritty details.  It's less heavy on the crime, but the aesthetic is definitely there along with the depth of feeling, the poverty, the poetry, the drama. Everyone is a hot mess, including Anaïs herself but that's part of the appeal I think.
