When Alexandria Marzano-Lesnevich was in law school, she did a summer internship at a Louisiana law firm. She was firmly against the death penalty, and then they asked if she would be prepared to work on the case of convicted child murderer Ricky Langley. Attempting to familiarize herself with the case, she was overwhelmed by memories of being molested by her grandfather—and though her career as a lawyer was pretty much over before it had even begun, her future as a writer was just beginning.

In The Fact of a Body, Marzano-Lesnevich writes about her efforts not just to confront what had happened to her and her sister, and how her family had suppressed it, but also to understand Rickey Langley—not to sympathize with him, as we discuss in this interview, but to understand what drove him to commit his crimes... and how his attempts to seek help before then had gone unanswered.

During our conversation, she also described one of the long-term effects of her grandfather's molestation, how even as an adult her body would sometimes "freeze up" in a dissociative state—and how, since the writing of this memoir, that had stopped. It led us to discuss the clich&@33; about memoir writing, which is that it's supposed to be cathartic, a notion she vigorously challenged. We also talked a lot about the true crime genre, from the reasons writers choose to write about certain crimes to the creative effort that goes into developing a narrative rooted in the bare facts of a case.
