Kiss of Death (audio story)

 was the one hundred and forty-seventh story in Big Finish's monthly range. It was written by Stephen Cole and featured Peter Davison as the Fifth Doctor, Sarah Sutton as Nyssa, Janet Fielding as Tegan Jovanka and Mark Strickson as Turlough.

Released in May 2011, it was the second story in a series of three stories featuring the Fifth Doctor along with Tegan, Turlough and an older Nyssa who had re-joined them in 2010's previous series of three audio stories. This story notably features more information on Turlough's past and background, more so than in his departure story Planet of Fire.

Publisher's summary
''The TARDIS travellers take a break on the beach world of Vektris. Hot sun, cold drinks and all the time in the worlds. What could possibly go wrong?''

A kidnapping, a spaceship heist and a desperate chase to a distant galaxy later, Turlough finds himself in a strange winter palace... along with a face from his past. The Doctor, Tegan and Nyssa, meanwhile, fight to escape its frozen catacombs, guarded over by a vast and deadly alien Morass.

But what connects Turlough to the ancient treasure hidden somewhere in the palace? And how far will he go to acquire it?

Part one
Slippage in the TARDIS's physical vector generators has left the Doctor, Tegan, Turlough and Nyssa on Vektris for two days and nights and the Doctor tries reformatting the interior dimensions. Turlough answers the door of where Tegan and Nyssa are staying to Deela, an old Trion friend who tells him that she is being used by Hoss and Kanch to lure him out. Kanch sedates him and takes him to their warp jet where Deela explains how Calquin Rennol needs them both on the Winter Planet.

Turlough is followed by Tegan and Nyssa and spotted by the Doctor. They take a mining ship and reroute the gravity wells to boost the engines and allow them to keep up with the warp jet, which lands at the Winter Palace sequestered from Turlough's family by Deela's father when war broke out. Rennol orders Turlough and Deela to kiss to open a dimensional vault, but it does not work and the group are interrupted by an alert warning them of the mining ship's approach. Hoss shoots the ship and the Doctor, Tegan and Nyssa brace themselves for impact.

Part two
The Doctor cushions the ship's fall using the gravity wells, but it starts collapsing after impact and Nyssa falls into a series of tunnels from which he goes to save her.

Turlough explains that he and Deela found the dimensional vault, apparently stolen by his great-grandfather, and he set it to be opened by a random mingling of his and Deela's DNA, hence why Rennol needed to bring them together to get inside it.
