A young woman is found strangled in an Oxford college the morning after it hosted a Gulf state ruler whose human-rights record does not bear scrutiny. DI Ryan Wilkins, trailer-park raised and furiously class-conscious, is not the kind of detective who looks the other way. His partner Ray Wilkins, Balliol-educated and impeccably suited, knows which doors to open and how. Mason sets them against each other as much as against their suspects. Shortlisted for the CWA Gold Dagger in 2023, and the most purely enjoyable debut crime novel of that year.
