Perfect for you if...

You love cosy mysteries with genuine puzzles to solve, not just window dressing for character drama.
You're already invested in Judith, Suzie, and Becks and want to see them tackle their toughest case yet.
You appreciate British settings and procedural details that make murder investigations feel real and absorbing.

Maybe not for you if...

You need high stakes or dark themes. This is a classic whodunit with warmth, not a gritty crime thriller.
You haven't read the first two Marlow Murder Club books and prefer starting series at the beginning.
You find amateur detectives tiresome or prefer police protagonists working by the book.

About this book

Geoffrey Lushington, Mayor of Marlow, dies suddenly during a town council meeting. When aconite—known as the queen of poisons—is found in his coffee cup, the police determine he was murdered. The police bring Judith, Suzie, and Becks in as civilian advisors from the start, giving them freedom to interview suspects and follow leads. The Marlow Murder Club must determine who killed the affable mayor and how the poison reached his coffee. As the investigation unfolds, they face questions about whether others are in danger. This case proves to be their most difficult yet, particularly as Judith disregards standard procedure in pursuit of answers.
