Jon Culshaw reads this epic novelisation of an original radio adventure for the Third Doctor. In Twentieth Century London the Doctor and UNIT are called to investigate a grisly murder at Space World, a futuristic new theme park on Hampstead Heath. Tagging along, journalist Sarah Jane Smith and her photographer colleague Jeremy soon find themselves facing huge crab-like creatures, mind-controlling devices and vicious flesh-eating beetles. And those are just the attractions... It is the beginning of a terrifying adventure that leads them to distant planets and deadly situations. Jon Culshaw reads Barry Letts's novelisation of his 1993 BBC radio serial starring Jon Pertwee, Elisabeth Sladen and Nicholas Courtney.
