Two months before Sarah's twin sons leave home for their gap year travel, her husband Andrew, a keen amateur thespian, announces that he's leaving her for his leading lady. Happily married for the past twenty years, Sarah has no idea how to play the role of discarded wife. If only there was some kind of guide to tell her what to do! For as Sarah is to discover, the way forward is strewn with hazards and humiliations. Fortunately help is at hand in the form of her friend Miriam, a host of well-meaning neighbours, a misbehaving mongrel and an unassuming plumber. And when Sarah takes on the role of Mrs De Winter in the forthcoming Ambercross Players' production of Rebecca, being single actually starts to get more interesting than she could have imagined.
