Herbal Homicide
by Fiona Grace
2024
Herbalist Penny Hawthorne travels the world for rare ingredients, but in the Swiss Alps a death makes her the prime suspect. With help from a British detective, she investigates the bitter rivalries behind the crime to clear her name.
Series background & context
Penelope Hawthorne, known as Penny, is an herbalist who creates unique teas and keeps chasing the next perfect ingredient. Her work takes her to far-flung places, where she hunts rare herbs, roots, and blends that most people have never heard of.
Travel is the dream. Murder is the surprise.
The series starts with Herbal Homicide, when Penny is in the Swiss Alps and a death makes her a prime suspect. To clear her name, she has to lean on her sharp senses, her knowledge of plants, and a willingness to question everyone, even the people who seem most charming.
These books feel like cozy mysteries on the road. Each case is tied to a location, a culture, and a small circle of suspects, and Penny’s tea-making expertise becomes a practical way to think about clues: what’s been mixed, what’s been hidden, and what leaves an aftertaste.
A recurring romantic thread adds warmth, especially when a dashing British detective shows up as an unexpected ally. The stakes stay personal: reputation, freedom, and the ability to keep living the life Penny loves.
Start with Herbal Homicide and follow the series in order for a mix of travel atmosphere, gentle humor, and mysteries that steep slowly before they boil over.
