After two-parter
The Magician's Apprentice and
The Witch's Familiar kicked the latest season off with a bang, this week sees
Doctor Who move back into more familiar territory with a good old fashioned "base under siege" story. Under the Lake was written by
Being Human writer
Toby Whithouse, who's previous forays on Who include the episodes
School Reunion,
Vampires of Venice,
The God Complex and
A Town Called Mercy. Certainly an interesting resume, which quite a variety of episodes. School Reunion however happens to be a particular favourite of mine.
