THE Curse Of Fenric
More Germans, ah but this time, Viking ruins, Russians, and yes, Vampires, or Vampire like beings.
Fenric turns out to be an old old enemy of the Doctor, and they had played a deadly chess match, again challenged, the Doctor almost outwits Fenric but Ace, unknowingly gives away the secret. This entire serial is based on belief. If your faith is strong, you will prevail. I thought at once, the chess game was going to be like "The Seventh Seal", one of Bergman's great films, but a different turn, changed it all.
Not the best of Doctor 7, but watchable
