When a distress call from an unknown source threatens to rip the TARDIS from the vortex, the Doctor and Peri arrive in nineteenth-century Africa hoping to find the cause of the disturbance.

With Lonely posing as his gentleman's gentleman, the section's top operative David Callan is sent to a country estate in Northumberland to infiltrate a rich men's shooting party. One of his companions is an assassin but which one? High living and high stakes on the grouse moors as Callan attempts to work out which of the dead-shots is a man-hunter.1.2 File on a Classy Club by James Mitchell. (adapted by Peter Mitchell). Callan finds the odds are stacked against him when he poses as a high roller at London's top casino.
