The Valley of Death (audio story)

Publisher's summary
A century after his great-grandfather Cornelius vanished in the Amazon rainforest, Edward Perkins is journeying to the depths of the jungle to find out what became of his ancestor’s lost expedition. Intrigued by what appears to be a description of a crashed spacecraft in the diaries of that first voyage, the Doctor and Leela join him on his quest. But when their plane runs into trouble and ends up crash landing, everyone gets more than they bargained for.

The jungle is filled with giant creatures and angry tribesmen, all ready to attack. But in the famed lost city of the Maygor tribe, something far, far worse is lurking. Something with an offer to make to mankind. Who are the Lurons and can they be trusted? Will the Doctor defeat the plans of the malevolent Godrin or will he become just another victim of the legendary Valley of Death?

 * Leela and Edward are incapacitated through the use of a poison dart tipped with a paralysing agent which she erroneously believes to be a janis thorn. After regaining consciousness, she tells Edward that the face of Xoanon was carved into a mountain on her native planet. Furthermore, she mentions that she is easily at home in a jungle as she comes from one. (DW: The Face of Evil)
 * The Fourth Doctor was previously duplicated by the Kraals, who created an android copy of him as part of their attempted invasion of Earth. (DW: The Android Invasion)
 * Leela refers to her temporary blindness, which resulted from witnessing the destruction of the Rutan Host's mothership over Fang Rock in the 1900s. (DW: Horror of Fang Rock) She would be blinded once again, for a considerably longer period, during the Gallifreyan Civil War (BFG: Fractures) but her sight was eventually restored through the transfusion of Vampire blood on the Gallifrey of an alternative timeline (BFG: Annihilation).
