Not doing anything tonight? Go listen to Donald H. White, author of the recently released book The Black Dahlia Files, explain his theory about the decades-old mystery. As the publisher says, Wolfe “assembles all the missing pieces of the Black Dahlia murder puzzle and names the notorious psychopathic murderer who once wandered the labyrinthine corridors of power that crisscrossed the shadowy underworld of the City of Angels.” I love flap copy. Anyway, it’s at the LA Press Club HQ at 4773 Hollywood Blvd. at 6:30, and it’s free. More info here. You’re supposed to RSVP, but, frankly, RSVPing is for wussies. Just show up.
