“A must-have series for middle-grade readers.” ―Booklist

In the third book in R.A. Spratt's hilarious Friday Barnes Mystery series, crime hits close to home when Friday Barnes learns her mother has been kidnapped. But her detective work gets put aside when Friday is distracted by other happenings at school: a new VIP student (a Norwegian princess!) has just arrived and a master thief called the Pimpernel is causing chaos across campus. Can super sleuth and girl genius Friday crack the case of her missing mother, reign in a royal brat, and unmask the elusive Pimpernel?

Big Trouble: A Friday Barnes Mystery brings the same wit and humor that kept readers puzzling and laughing in Friday Barnes, Girl Detective and Friday Barnes Under Suspicion.
