Doctor Who - Past Doctor Adventures - 64 - Scream of the Shalka

When the Doctor lands his TARDIS in the Lancaster town
of Lannet, in the present, he finds that somehing is terribly wrong. The
people are scared. They don't like going out onto the streets at night,
they don't like making too much noise, and they certainly don't like
strangers asking questions.

What alien force has invaded the town? Why is it watching barmaid
Alison Cheney? And what plans does it have for the future of the planet
Earth?

The Doctor is helped (and hindered) by his new military liaison Major
Kennet and his Royal Green Jacket troops. His old enemy the Master also
plays a small part. During the course of this adventure he encounters a
brand new race of ferocious alien monsters, and strikes up a friendship
with his latest companion, Alison.

While starting with a small community under threat, this
old-fashioned, very traditional but very up-to-date Doctor Who story
takes in the entire world, from New Zealand to India, Siberia to the
USA, and cosmic expanses beyond.
