The Spectre Of Lanyon Moor

The Doctor and Evelyn arrive in Cornwall and encounter a very special old friend, apparently helping out with a local archaeological dig. But Brigadier Lethbridge-Stewart has another agenda which has been laid down by his old employers, UNIT.

Evelyn meanwhile strikes up a friendship with the local aristocracy in the form of Sir Archibald Flint and the Doctor decides to go digging about in an old fogou.
