The Secrets We Hide (2026) is the second installment in Karin Slaughter’s North Falls series, following We Are All Guilty Here (2025), which introduces North Falls, Georgia, and police deputy Emmy Clifton. In that first novel, Emmy investigates the abduction of two teenage girls, a case that also brings her into contact with her estranged sister, Jude Archer, a former FBI profiler who had been away from North Falls for decades. The Secrets We Hide opens on a new case, the murder of a retired detective, but keeps the same setting and central pair, letting their partnership develop further rather than restarting the main characters’ dynamic from scratch.

Slaughter built her reputation on two long-running series, Grant County and Will Trent, both known for pairing procedural plots with family drama centered on institutional failure and buried personal history. North Falls extends this pattern but shifts focus from a single lead investigator to two sisters whose professional backgrounds, one in local law enforcement and one in federal investigative work, complement a fraught shared history. Readers familiar with Slaughter’s other work may recognize this structural choice since her novels often pair professional partnerships with strained family or romantic ties, as with Sara Linton and Will Trent.

Although The Secrets We Hide can be read as a standalone novel, knowing Emmy and Jude’s history informs the complexity of their dynamic. Their reconnection in the first book, and Jude’s decision to keep a secret from Emmy—that she’s Emmy’s biological mother—continues to shape the second. Consequently, their working relationship is tentative and prone to conflict, raising the emotional stakes of their investigation.
