To celebrate the fiftieth anniversay of everyone actually finding out about how good Doctor Who was and actually starting watching it (it took a couple of weeks to catch on...), here's a little puzzle. Once you've solved the puzzle don't expect great things from the cache - you'll be disappointed... it's a dull magnetic nano. Sorry...
You'll find the cache at
N [(A2)(C2)] [(A4-H3)(B9)].[(F2)(C2)(B8)]
E [(A7-G4)(B2-I1)] [(E9)(C4)].[(F3)(G9)(G5)]
