Doctor Who: The Fourth Doctor Adventures Series 15: Lethal Progress

The Doctor takes the TARDIS into the future, where many great scientific leaps are taking place. But every new advance has its risks - and some of these risks are deadlier than others. 15.3 Green and Pleasant Planet by Tim Foley The Doctor and Sarah find themselves exploring an alien world alongside a British space expedition. It's never been visited before... so what's a model village doing on the surface of the planet? Finding the answer may prove deadly. 15.4 The Continuum by John Dorney The Doctor and Sarah land on the space-station Daedalus on the day it makes history. The first journey through hyperspace has just been completed. But it hasn't gone as smoothly as posterity suggests. Something terrible is happening - and the clock is ticking down. 15.5 The Audience by Lizzie Hopley A cultural festival on Gakoria should be light relief for the TARDIS crew. But when one of the cast of a play dies, Sarah has to join the troupe. And the Audience on this world are very demanding. Because on this planet... the play's the thing.
