Prison governor (Frontier in Space)

A prison governor of Earth's Lunar Penal Colony in 2540 once interacted with both the Third Doctor and.

Biography
The governor principally investigated the claims that the Doctor and Professor Dale had attempted to escape the prison on their own. He did not believe that they had in fact been set up by Cross, a prisoner who enjoyed the governor's favour.

When the Master, posing as a commissioner from the dominion government of Sirius IV, requested that the Doctor be turned over to him, the governor at first claimed greater right to the prisoner, and refused. However, when the Master threatened to reveal the whole trial as a farce, the governor relented and released the Doctor into the Master's custody. (TV: Frontier in Space)

Behind the scenes

 * The novelisation greatly reduces the governor's role in events. There is no trial at the Lunar Penal Colony; instead, the governor meekly recognises the president's authority and turns the Doctor over to the Master.
 * The governor was unnamed on-screen, but was called Stevens in the script. (INFO: Frontier in Space)
