Heretic

Two Mormon missionaries, confident Sister Barnes and timid Sister Paxton, arrive at the home of a reclusive Englishman, Mr. Reed. Reed invites them into his home, but the missionaries are hesitant to be alone with Reed. He assures them they are not alone because his wife is preparing a blueberry pie in the back of the house. They enter and begin to discuss religion, with Reed making several uncomfortable comments about the Mormon faith and the nature of belief. When Reed steps out of the room, Barnes realizes that the smell of blueberry pie is from a candle, the front door is locked, and they have no phone signal
