As this character-driven novel opens, Beatrice Macmillan, KC, is buying flowers for a dinner party, one she has planned for a group of people who haven’t seen each other for some thirty years, ever since the then-close friends gathered to celebrate finishing their university careers. That weekend party at a country house abruptly ended their friendship when one of them lay dead and another was arrested for his murder. Though he has never stopped claiming he was innocent, Tyler Green has been in prison ever since. Only recently has he been allowed to leave prison on parole. Beatrice has agreed to host their reunion at her large London home, though she’s uncertain why Tyler wanted to call them together. As nervous as she is about the event, nothing could prepare her for how it actually turns out, or what secrets will be spilled out in the process – along with more blood.
Though the group had believed they would remain close friends forever, Leo’s murder put their relationships to an end and they have since grown in different directions. Beatrice is a highly successful corporate lawyer, married to a prominent politician. Ali and Will have married, though originally Ali was deeply in love with Tyler. Ellen has had five children and lives a seemingly idyllic life in the country. Clara has come out as a lesbian and has married another woman, though she anxiously checks in on Jay, who has never recovered his equilibrium after the murder. Rudi is a writer, supported by a wealthy wife, but he’s struggling to finish the novel he’s working on. Marco, in turn, has never managed to turn his musical talent into a successful career. He brings his current brash and outspoken girlfriend with him to the reunion as they all assemble. The beautifully-catered meal in Beatrice’s magazine-perfect home becomes an almost comically disastrous event, with too much alcohol consumed and too many suppressed emotions let out to run rampant once Tyler arrives.
Tyler doesn’t drink – it would be a violation of his conditions for release – and he isn’t interested in friendship. He wants to meet the people who left him behind when he was convicted of murdering a man who, it becomes clear, gave reason to be disliked by them all. Tyler wants to observe their reaction as he announces he didn’t kill Leo, but someone in the room did.
While the setup is a variation on the classic locked-room mystery – a small group of suspects is somehow trapped together as a crime is committed and solved – the focus is less on plot than on developing each of the characters. While it’s a large cast, it’s not hard to keep them all straight given how each has a unique story, stories that twist and turn throughout the nightmarish evening that will end in yet more violence. It’s then that Detective Maud O’Connor is called in to lead a fraught investigation against a backdrop of political pressure, a media maelstrom, and a superior who doesn’t care who is guilty so long as the case is resolved quickly.
Previous novels featuring Maud O’Connor – Has Anyone Seen Charlotte Salter (2024) and The Last Days of Kira Mullen (2025) – followed the same pattern of establishing a set of characters who fill the first half with deeply-realized stories leading up to the arrival of the detective who will sort it all out. She’s a catalyst of a character, prying out the secrets being withheld while doing battle with a system that puts obstacles in her way. While these are not the kind of thrillers that depend on lots of action and short cliff-hanger chapters, they cleverly ramp up tension as the pages turn. In this case, we get to watch a dinner party go completely and extravagantly off the rails before Maude arrives to pull pieces of information out of the rubble to make sense of it all. For the reader who isn’t looking for quick thrills but enjoys a deeply-imagined world with psychologically acute character development and a winningly independent detective, it’s a treat.
