A Tale of Three Cities

I've had a busy day starting at an unholy time which felt like the middle of the night!
I flew from Edinburgh to London for some meetings (two cities) then jumped on a train up to Leeds for an overnight stay (making the hat trick)
I watched this scene unfold in front of me in London.
A radical( fun)da(mentalist) carpenter was using a cunning disguise to sneak up on and overpower the two policemen.
Luckily the boys in black were highly trained and simultaneously pointed to the ground and said "is that a fiver down there?"
The carpenter shouted "it's mine.....d'oh" and gave his position away.
