Goth Opera by Paul Cornell

Humanity's time on the Earth is nearing its end, the Long night has begun and an age of the undead has arrived.

1993 in the city of Manchester and the vampires of Great Britain have received a message, the long awaited arrival of their messiah is nigh, now is the time for recruitment.

Meanwhile the Doctor and his companions are enjoying a well earned holiday in Tasmania when Nyssa is attacked by a demonic child. She manages to fight off the beast and escape unharmed except for two small puncture marks.

Why are the descendants of the Great Vampire so desperate to obtain the blood of a Time Lord? And what is their connection to a forbidden ancient Gallifreyan cult?
