Ghostwriter is a television series about a group of New York City teenagers who solve mysteries with the help of an invisible ghost. The ghost can only communicate to the teens by manipulating letters on everyday objects and using them to form words and sentences. The show aired on PBS from 1992 to 1995 and was co-produced by the Children’s Television Workshop and the BBC.

The series was intended to teach reading and writing skills to kids. Young viewers were encouraged to use the reading and writing clues given in each mystery to attempt to solve them just as the Ghostwriter team does in the show.

Ghostwriter was critically acclaimed and by the end of its third season, it ranked in the top five of all children’s shows on American television. The program was cancelled after the third season due to lack of funding. Ghostwriter has been broadcast in 24 countries worldwide, and generated a number of foreign-language adaptations.
