Holly Jackson

Holly Jackson is a British young adult author best known for A Good Girl's Guide to Murder, beginning with the 2019 novel of the same name, which follows high schooler Pippa Fitz-Amobi as she reinvestigates a local murder for a school project and uncovers a case far more dangerous than the official version of events. The trilogy, later extended with a fourth book, As Good as Dead, built a large readership for its true-crime-podcast structure -- interview transcripts, case files, and investigation logs woven into the narrative -- that mirrors how real amateur sleuths document their work online.

Jackson studied creative writing at university before her debut's success let her write full time, and she has continued in the same YA thriller register with further standalone and series titles built around similarly resourceful teenage investigators. The Good Girl's Guide books in particular are credited with helping popularize true-crime-influenced structure within YA mystery fiction more broadly.

A new reader should start with A Good Girl's Guide to Murder, which sets up Pip's investigation and the series' documentary-style format. The trilogy was adapted into a television series that premiered on BBC Three and Netflix in 2024.
