We have a 4-way tie with tyke 11, jon 28, mattrom 26 and fiery 33 all on 2 votes. Looking at the votes of those four only, fiery 33 got 2 votes compared to 1 each for paul 28 and amej 35. That seems as good a way as any to pick a winner from 4 nice clues, so gold goes to fiery 33 for the nifty subtractive:
Mug goes down a road leading to jail (4)
Well done fiery and thanks all for playing.
Longish but interesting:
