When a series of women are found brutally murdered, the London police department is reluctant to admit they might have a serial killer on their hands. Police detective Maeve Kerrigan is pulled into the investigation, but instructed to keep all information about the case away from her partner, DI Josh Derwent. Aspects of this case resemble a murder Derwent was involved with as a teenager, and though Maeve thinks it’s ridiculous, her partner may be a suspect. But as Derwent’s behavior becomes more erratic, Maeve is forced to ask herself how much she really knows—or trusts—her partner.
Jane Casey’s been on a roll with her Detective Maeve Kerrigan series, and her latest is just as thrilling as previous installments. The Stranger You Know focuses on the background of DI Derwent; at the beginning of the series, he was my least favorite character. His arrogance and misogyny would have me raging against him. But over the course of the novels, somehow he’s grown on me (a testament to Casey’s excellent character writing and development), so this novel was a very welcome look into this strange man. Casey keeps the atmosphere taut; like Maeve, readers can’t be quite sure that Derwent isn’t involved in the murders. The twists and turns in the story will leave readers guessing, and though it feels as though there are one too many suspects towards the end of the book, it’s still very entertaining from beginning to end. Readers looking for a new crime series would do well to pick up Jane Casey’s books as soon as possible.
