We've seen a couple now. I always found Christie a dull read, but she works fabulously on the small screen.
Murder At The Vicarage spent a leisurely three quarters of an hour establishing the 1950s rural idyll that is St Mary Mead and then tore it to
shreds as it was revealed that all these prosperous, respectable middle-Englander stereotypes are in fact murderers, adulterers, thieves, embezelers and traitors.
In her own way Christie is as subversive as Bunuel. Something like Murder At The Vicarage is really just The Discreet Charm Of The Bourgeoisie by other means.
