Dr Shearsmith was a resident of Crook Marsham. He and Jack Prudhoe were the first two people to disappear from the village after the Sentience began to fully manifest. (PROSE: Nightshade)
Behind the scenes Edit
Shearsmith is likely a reference to Reece Shearsmith, one of Mark Gatiss' co-creators and co-stars in The League of Gentlemen, whom Gatiss mentions in the afterword to Nightshade.
