Knight on shining bicycle

I've never met Franny Armstrong, though her brother is a good friend and I certainly admire her dedication to doing something about climate change. 

But getting rescued by the Mayor of London, on his bike no less, is a story too good to pass on.  Thankfully Franny was not hurt.  And, yet a bit shaken by the attempted mugging, Franny still managed to grill him on climate change policy!
