What picture would you take to sum up London? Perhaps the skyline with the distinctive Swiss Re tower, or perhaps the Houses of Parliament, maybe Tower Bridge, the Changing of the Guard might be good. The pic below is London encapsulated for me - snapped in passing with a camera phone.
Some doe-eyed innocent had u-locked their bike to iron railings one morning, but rather dopily put the lock through the front wheel only, you see all that was left of the bike later in the afternoon.
If you look carefully there is evidence pointing to the thief. Watch out for London pigeons; They are greedy, violent, untrustworthy and organised.
