San Diego Case Files Books in Order

The San Diego Case Files series moves the action to the California coast and pairs homicide detective Katherine Kit McKittrick with court appointed psychologist Sam Reeves. Where some of Karen Rose's earlier books revolve around small towns, these stories dig into the secrets of affluent suburbs, retirement communities and political power circles.

Cold Blooded Liar opens the series when Sam, troubled by what one of his patients seems to know about a string of unsolved murders of teenage girls, calls in an anonymous tip to the police. The move backfires spectacularly when Kit tracks the call and hauls him in, furious that a stranger is meddling in her cold case. Once they compare notes, however, it becomes clear that Sam's client may hold the key to identifying a sadistic killer who has hidden in plain sight for years.

In Cheater, Kit is called to Shady Oaks, an upscale retirement community, after a resident is found stabbed and his apartment ransacked. The victim's tidy life hides a messy tangle of old grudges, missing money and long simmering anger. Sam, who volunteers at the facility in memory of his grandfather, already knows many of the residents and reluctantly teams up with Kit again, even as both of them struggle with the emotional fallout from their first case.

Dead Man's List raises the stakes further when Kit and Sam, finally trying to go on a normal second date, literally stumble across the mutilated body of a local politician. The investigation exposes a shadowy group that keeps a kill list of influential targets and uses hired assassins to erase problems. As witnesses begin to die, Kit's team must navigate San Diego's social elite, media frenzy and their own department's politics to keep ahead of whoever is crossing names off the list.

Planned series entry Family Lies turns the focus closer to home when Kit's foster sister Akiko is contacted by a woman claiming to know her birth mother. A meeting that was supposed to bring family answers instead ends with Kit shot and the woman dead, dragging both sisters into a dangerous puzzle of inheritance, grudges and past abandonment. Even on medical leave, Kit cannot stop digging, and Sam is right beside her as another case turns into a personal reckoning.

Across the San Diego books, Rose leans into themes of chosen family, the long tail of childhood trauma and the ways violence seeps into even the prettiest neighborhoods. Kit's big, chaotic foster clan and Sam's quiet determination to do right by his patients give the series a warm core that balances its serial killers, political scandals and high body counts.
