1. I begin my journey on the Northern Line, not too far from home in the deepest tube station of all. It's worth surfacing, though, to see all of the greenery and hike up Parliament Hill. Where in London am I? Mornington Crescent Hampstead Kentish Town Belsize Park

2. After having a picnic, I decide to head travel on the Piccadilly Line until I reach a place that Dickens knew well. I have to see a lawyer friend of mine so I head over to Gray's Inn Fields for a spell before returning to the busy streets. Which part of London am I in now? Mornington Crescent Warren Street Holborn Tottenham Court Road

3. As I'm in the center of town, I decide to jump onto the Central Line and travel West. I decide to stretch my legs at a stop that is overwhelmed with tourists carrying travel books. Knowing the way, I rush past them toward the market to buy my mother an antique jewelry box for her birthday. Where in London can I find such a market? Bond Street Oxford Circus Mornington Crescent Notting Hill Gate

4. From here, I hop on the District Line only because it happens to arrive before a Circle Line train. I alight randomly and as I ascend the stairs unto the street see the Houses of Parliament directly in front of me. Where in London am I? Embankment Mornington Crescent Westminster St James's Park

5. As I'm feeling rather touristy after seeing Parliament and Westminster Abbey, I decide to hop on the Jubilee Line until I come to the stop nearest the London Eye. Where have I stopped? Waterloo Embankment Mornington Crescent Southwark

6. Feeling as though I've done the tourist scene, I decide to take the Bakerloo line north from Waterloo. At my stop I surface and take a look around. The atmosphere inspires Christian charity, so I give 50p to a homeless man and carry on walking into a large Borders bookshop where I plan on purchasing a London A-Z. Which part of London am I in now? Oxford Circus Piccadilly Circus Mornington Crescent Charing Cross

7. I've bought my A-Z and now it's time to keep moving. I switch to the Piccadilly line just for a change and head to a station that is currently undergoing major renovation. It's a place of tragedy - housing memories of a catastrophic fire and terrorist attack - but also a place of magic. Which tube station am I in? Camden Town Mornington Crescent King's Cross St. Pancras Russell Square

8. It's time to begin the journey home, so I jump back on the Northern line heading north. I don't get very far, though, before the combined smells of foreign food, cannabis and sewage grab my attention and I exit into the middle of the second market of the day. Which lively bit of London am I in now? Camden Town Kentish Town Mornington Crescent Chalk Farm

9. Before heading home, I backtrack slightly for the sake of fun and arrive at a station that was nearly closed for good in 1993. I don't leave the tube station, but instead wander around it and appreciate the work that's been done and admire the blue tiling that surrounds me. A beautiful London underground, but which one? Mornington Crescent Warren Street Euston Chalk Farm

10. One final journey on the Northern Line brings me home. As I exit the station, I find myself on a busy high street with cars whizzing past. I can turn left and visit Poundstretcher or turn right towards the popular music venue, The Forum, and towards home. It's late and I'm tired, so I turn right. But what London tube station have I exited? Kentish Town Belsize Park Tufnell Park Chalk Farm
