The Black Guardian strikes a deal with a British student named Turlough. He will return him to his home planet if Turlough will kill the Doctor for him. Meanwhile the Doctor, Tegan and Nyssa are near Turlough's school, trying to repair a hidden device that has the TARDIS trapped in perpetual orbit, when they run into an old friend of the Doctor's... twice. Can the Doctor avoid the machinations of both Turlough and the mutated alien scientists while keeping the two Brigadiers from different time zones from meeting?
Did You Know?
Turlough was originally going to be introduced in a story called "The Song of the Space-Whale" by Pat Mills
and John Wagner
. The story concerned a group of people living in the belly of a giant whale in space. The Doctor would find this out while attempting to protect the creature from being slaughtered by a rusting factory ship. The castaways living in the whale, as well as the ship's captain, would be working class characters, with the former's dialogue being based on that of a working-class Northern Irish family that Mills knew. A disagreement between Mills and Eric Saward
led to the script being delayed until it was too late to serve as Turlough's introduction. See more
