Writer Susan Orlean made a name for herself with books like "The Orchid Thief," "Rin Tin Tin" and "Saturday Night."
Her new book is of a different sort, it's all about a mysterious character who lives in downtown Los Angeles: the Central Library. We’ve been checking in with Orlean from time to time as she researches the fire an arsonist set in the library book stacks in the 1980s.
Host Alex Cohen sits down with her again to talk about the role arson investigators play in the story.
