When a terrified socialite dies in their office, whispering a name from Len's past, Dahlia Langford, the gumshoe trio from "Shadows and Smoke", Los Angeles' newest detective agency, is plunged into a labyrinth of corruption, twisted obsession, and government-sanctioned horrors. From the smoky jazz clubs of Sunset Boulevard to the rotting warehouses of the docks, Len, Mira, and Jack uncover Project Silver, and the Black Dahlia Revues, where the dead aren't dead and the missing find them.
