She Was Found in a Guitar Case, the new novel by David James Keaton, opens in a way that might seem familiar to fans of crime fiction. The novel’s protagonist learns of his wife’s death, and sets out to learn the truth about it, along with several mysterious connections she may have had. Things escalate quickly from there, with the narrative doubling back on itself and taking on a tone that’s both agreeably shaggy and increasingly paranoid. (If there’s a sweet spot between Pynchon and Portis, this book finds it.) I talked with Keaton about the novel’s genesis, how locks on bridges informed the book, and this book’s long path to publication.
