Pemberton (Nightshade)

Mr Pemberton was a resident of Crook Marsham. He worked at the local post office and had never been more than thirty miles from there. He was one of the villagers consumed by the Sentience in December 1968. (PROSE: Nightshade)

Behind the scenes
Pemberton is likely a reference to Steve Pemberton, one of Mark Gatiss' co-creators and co-stars in The League of Gentlemen, who Gatiss mentions in the afterword to Nightshade. Pemberton later played Strackman Lux in TV: Silence in the Library / Forest of the Dead.
