O Is for Outlaw was published by Henry Holt in 1999. Kinsey buys a box of her own belongings at a storage unit auction — items from her first marriage to Mickey Magruder, a cop she divorced under painful circumstances. Among the contents: evidence that Mickey may have been framed for the assault that ended his career. Kinsey is forced to reexamine her own history, her judgment, and the question of whether she abandoned someone who needed her.
The novel is the series’ most personally resonant: Kinsey confronting her own past rather than a client’s, questioning her own reliability as a witness to her own life. The investigation of Mickey’s case becomes an investigation of Kinsey herself.
The Unreliable Self
Grafton uses the storage-unit discovery to ask a question that most detective fiction avoids: what if the detective is wrong about her own history? Kinsey’s certainties about her first marriage — that Mickey was guilty, that she was right to leave — are systematically undermined. The novel is a meditation on the stories we tell ourselves about our own lives.
