Highgate (The End of the Beginning)

Highgate was a reformed vampire. The Doctor showed him the straight and narrow but checked in on him every 30 years. In 1999 the Eighth Doctor came to check on him, Highgate told him of a rogue vampire Dwayne Pherber. He helped to defeat Pherber, and then committed suicide realising that he had lived all he wanted. He gave the Doctor a gift he was once given by Gostak (AUDIO: The End of the Beginning)
