Forty (audio series)

Forty was a subseries of The Fifth Doctor Adventures, published by Big Finish Productions, which celebrated 40 years of the Fifth Doctor, played by Peter Davison. This short audio series was made to pay homage to Davison's own career, and to all the companions who'd been with him as the Fifth Doctor transformed into the man he'd become by The Caves of Androzani.

Forty: Volume 1 introduced the premise: the Doctor is being pulled along his own time stream, to various points within his fifth incarnation. Two versions of the Doctor actually star in this first anthology: a younger Fifth Doctor, who discovers that Adric is gone and Tegan had left the TARDIS, to come back again, and an older Fifth Doctor, who gets the chance to correct his past behaviour toward Adric. The first adventure, Secrets of Telos, is a return to Telos in a sequel to TV: The Tomb of the Cybermen, and on the flip side, God of War introduces the Ice Warriors to the Vikings of 9th century Iceland. Both stories end on a cliffhanger with the Doctor getting pulled along his time stream all over again, leading into the next anthology.

A second volume was released on 7 September 2022, with a single entry involving the Nestene Consciousness and entitled The Auton Infinity.
