The Penny Hawthorne series follows an herbalist and tea expert whose knowledge of plants and infusions helps her investigate mysteries. With sixteen books, it’s one of Fiona Grace’s most substantial series, blending herbal lore with cozy mystery plotting. The titles — Herbal Homicide, Peppermint Peril, Chamomile Calamity, Earl Grey Alibi — signal the tea-and-herbs theme.
Penny’s expertise gives her a natural investigative advantage when crimes involve poisoning, botanical evidence, or the social world around tea shops and herb gardens. The series appeals to readers who enjoy specialized knowledge as part of their mystery-solving, similar to how Grace uses antiques in the Lacey Doyle books and chocolate in the Millie Swiss series.
