Black Widow by Chris Brookmyre

After a scandal leaves a brilliant but abrasive surgeon hounded by online trolls, she marries in haste; when her new husband dies in a suspicious car crash, blame quickly turns her way. His sister enlists a disgraced investigative journalist to dig into what happened, leading him through a web of digital footprints, medical rivalries, and conflicting witness accounts. As unreliable narratives stack up, the investigation exposes the corrosive effects of misogyny and reputation, forcing a razor-edge question: is she a manipulative killer or a victim of circumstance?
