Slipback by Eric Saward was the first original Doctor Who serial to be produced for radio. It was first broadcast by BBC Radio in the summer of 1985 when the televised series was on hiatus for a year. The broadcast formed part of the three-part children's magazine series Pirate Radio Four which featured two ten-minute episodes per edition.

Colin Baker and Nicola Bryant reprised their TV roles for the production, which also included other cast members. It, along with the earlier Doctor Who and the Pescatons, is considered a forerunner of the later Big Finish Productions audio dramas. It was followed nearly a decade later by two more radio dramas starring Jon Pertwee and in 2007 by a new made-for-radio series for BBC7 (produced by Big Finish) starring Paul McGann.

Slipback was released on cassette by BBC Audio, and later on CD by Silva Screen Records.


The Sixth Doctor and Peri share an adventure on board a starship taken over by its dual personality computer, which tries to take the ship back to the dawn of the universe and start life again. Along the way the duo meet a couple of comedy policemen, an art thief and a captain who wants to infect his crew with one of his diseases...
