Trixie Belden is a vivacious, 14-year-old tomboy who likes nothing better than adventure and solving mysteries. While one might expect her to lead a quiet life living with her parents and three brothers on Crabapple Farm, just outside Sleepyside-on-the-Hudson, New York, nothing could be further from reality! Trixie (short for Beatrix) and her best friend, Honey Wheeler, hope one day to have their own detective agency. As they tackle mysteries that have baffled authorities, the two girl detectives - along with other members of their club called the 'Bob-Whites of the Glen' - are certainly getting plenty of training!
