Tonight You’re Dead (Sandhamn Murders, 4)

Soon to be divorced, attorney Nora Linde is finding her way as a single mother, and even falling in love again, when she’s asked by her childhood friend Detective Thomas Andreasson to help in a disturbing investigation. Marcus Nielsen, a university student, has apparently committed suicide, but it’s what he’s left behind that’s so suspicious and damning: his research into the Coastal Rangers, an elite military group where, in 1976, a young cadet died under questionable circumstances, a sadistic sergeant went free, and a case went cold.

When two of Nielsen’s contacts are also found dead—and diaries of their tortuous training turn up missing—Thomas and Nora are certain that whatever happened three decades ago is unforgivable. And for someone who wants to keep those secrets buried—unforgettable. Now they must fight against time to expose a cover-up that hasn’t yet claimed its last victim.
