CW and daughter were watching the BBC North-East news and they shrieked, paused the picture, and summoned me over. The Master is working as a tourist guide in Whitley Bay under the name of Steve Reed. Immune to sunshine (what little of it there is in Whitley Bay in March, anyway) so perhaps he had some sort of evil Shansu. Or was brought back as a human by that ritual with the sacrificial vampires the way W&H did with Darla.
Either way, he's there. Be afraid. But probably not very afraid.
