This small but important road at the rear of Lincoln’s Inn Fields had fallen in to very poor repair. It was resurfaced just before Xmas 2012.
Whetstone Park crops up in Pepys diaries (16 November 1668) . He was chasing after his wife’s former maid Deb, with whom he had been caught having an affair. It doesn’t sound like a very salubrious place:
‘…away to Holborne, about Whetstone’s Park, where I never was in my life before, where I understand by my wife’s discourse that Deb. is gone, which do trouble me mightily that the poor girle should be in a desperate condition forced to go thereabouts’
