Jon Culshaw reads this common novelisation of Doctor Who’s special 20th Anniversary TV adventure, featuring the physician in each of his first five incarnations.

Each one has been removed from his time-stream and – with one unlucky exception – taken to the Loss of life Zone on Gallifrey. There they, along with a range of their devoted former companions, encounter many deadly road blocks including Daleks, Cybermen, Yeti, the Professional and a fiendish set of puzzles. Who’s the ultimate enemy they need to all unite to beat?

Predicated on Terrance Dicks’s epic TV experience, first broadcast in 1983, The Five General practitioners offered readers a chance to turn the clock back and satisfy some previous friends – plus some old enemies.
