Best friends tell you everything; about their kitchen renovation; about their little girl's schooling. How one of them is leaving the other for a younger model. Best friends don't tell lies. They don't take up residence on your couch for weeks. They don't call lawyers. They don't make you choose sides. Best friends don't keep secrets about their past. They don't put you in danger. Best friends don't always stay best friends.

Mr & Mrs Max Irving request the company of: Mrs Fran Friedman, mourning her empty nest, the galloping years and a disastrous haircut. Mr Saul Friedman, runner of marathons, and increasingly distant husband. The two Misses Friedman, Pip and Katy, one pining over the man she can't have, the other trying to shake off the man she no longer wants. At the marriage of their son James, forbidden object of troubling desire. For thirty-six hours of secrets and lies, painted-on-smiles and potential ruin. And drinks, plenty of drinks. There's nothing like a wedding for stirring up the past. As Fran negotiates her way from Saturday morning to Sunday evening she is forced to confront things she's long thought buried, and to make decisions about the future that will have far-reaching consequences for them all.
