Dalek scouting party

Some accounts held that a Dalek scouting party captured (PROSE:  The Astounding Untold History of the Greatest Enemies of the Universe) in the Valley of the Kings, in Egypt, (AUDIO: Mastermind) whereupon he was placed on trial for his life (TV: Doctor Who) by the Dalek Prelature and ultimately executed. (AUDIO: Mastermind)

A conflicting account held that the Master's trial arose when, in, the renegade came to Skaro of his own volition. (PROSE: The Eight Doctors)
