The Ultimate Evil (audio story)

 was the second and final story in the fifth series of The Lost Stories, produced by Big Finish Productions. It was adapted by Wally K Daly, from his original script, and featured Colin Baker as the Sixth Doctor and Nicola Bryant as Peri Brown.

This story was originally intended to be the second story of the original Season 23, but was cancelled along with other planned stories when Doctor Who went on a production hiatus.

Publisher's summary
With the TARDIS working perfectly, the Doctor and Peri decide to take a holiday. But where? A long-forgotten piece of equipment in the TARDIS storage locker sends them to the peaceful and idyllic continent of Tranquela - home of the Doctor’s old friend Ravlos.

But the land where they emerge is far from peaceful. A hate ray is regularly sweeping Tranquela, turning its inhabitants into savage beasts, and there is only one place it can originate - the planet’s other continent, home of Tranquela’s old enemies, the Amelierans.

Or is that the only place? Because somewhere far above the planet events are watched by the slimy super-salesman, Mordant, who has his own unscrupulous plans.
