Cassandra. Contentedly married to Dan. They rub along together in that sort of comfortable middle-years manner. Everything is pretty much 'normal' uneventful dull even. Then Ellie arrives in the village. Ellie is writing a novel & with her self-professed expertise in uncovering other people's secrets she always likes to place herself in the centre of the plot. Cassandra thinks she might be a little too much in the centre when she discovers that Ellie is writing about her Dan & their daughter Laura & it seems that Ellie wants Cassandra to know.
