Time travel, doppelgangers and a lady in red – take the Thursday quiz

Fourteen questions on general knowledge and topical trivia plus a few jokes every Thursday - how will you fare?

The quiz master is away, but do not fret. Before he left, a cache of documents written in invisible ink were entrusted to a secret operative in the Guardian offices, containing 14 questions on topical trivia and general knowledge. As usual, there's a hidden Doctor Who reference to spot, a picture of our beloved Kate Bush, and one round that has anagrams in it just to be annoying. Have fun. There are no prizes, but let us know how you get on in the comments.
