Brilliant work, Dan Druff’s time is running out!! As you walk around the platform at the Elephant and Castle there seems to be no clues. We need a break through. Wait MI5, the British spy agency have arrested Arthur Swag, a well-known criminal who loves buying stolen diamonds. He was heading to Highgate cemetery on the 'tube' to buy some Crown Jewels!!! Look at what was in his suitcase!

 

Q: Which underground tube station on the Northern Line would you have to get off to find Highgate cemetery? (Begins with A and ends in Y)
