Huffed on my first go of this round - good gracious me !!!
I'm nearly choking on these words as I say them but according to the 1972 post modern (*ach* *cough* *gasp*) ruleset, which I realise is a little sketchy in places, the huffing of another player currently north of the Thames and at a station beginning with M or N, actually and in reality, dehuffs the player and allows them to speed forth and double speed. Hence to Elephant and Castle ....... damn it, overshot!
