They feel that at last their own lives can begin … but they have no idea that they've been summoned into a tangle of fraying lives, from the OCD-suffering crossword setter who lives above them to their aunt's mysterious and elusive lover who lives below them, and even to their aunt herself, who never got over her estrangement from the mother of the girls - her own twin - and who can't even seem to quite leave her flat….
