Perfect for you if...

You loved the Downton Abbey era and want a cosy mystery that captures 1920s glamour without requiring you to know the previous six books.
You enjoy traditional detective work with a strong female lead who's genuinely clever rather than lucky.
You appreciate a murder that feels properly baffling, with suspects who have real motives buried in scandal and secrets.

Maybe not for you if...

You need your mysteries dark and gritty; this one prioritises charm and period detail over psychological depth.
You prefer standalone novels and don't want to wonder if you're missing character development from earlier books.
You like quick, stripped-back plotting; this has the leisurely pace of a golden age mystery, which means red herrings and slow reveals.

About this book

London, 1924. Posie Parker, Private Detective, is called to investigate the murder of Amyas Lyle, London's top young lawyer, who is found with his head in a box of poisoned saltwater. Working alongside Inspector Lovelace of Scotland Yard, Posie uncovers a complex web of motives: a society wife, a powerful father-in-law, jealous friends, irate colleagues, political entanglements, and hidden love affairs. As she discovers long-buried scandals and secrets, Posie follows a trail of mysterious notes referencing the sea and saltwater, leading her from London to the seaside resort of Whitley Bay. While Britain celebrates an Olympic summer, Posie pursues answers about who killed Amyas Lyle and works to protect those he left behind. She also navigates a potential holiday romance and grows puzzled by Inspector Lovelace's unusual behavior and changed appearance. This is the seventh book in the Posie Parker Mystery Series.
