Désiré Cordier - mild-mannered former librarian, put-upon husband, lover of boules - is losing his mind. Or is he? Happily tucked away in the Winterlight Home for the Elderly, Désiré is looking forward to a quiet retirement with the other forgetful residents, safe in the knowledge that no one knows he's faking his memory loss. And as if there weren't reasons enough to opt out of the modern world, it would be worth it just to see Rosa Rozendaal again - the love of Désiré's youth, the one who got away. But dementia isn't all fun and games. There's a former was criminal hiding out in the home; once-beautiful Rosa might be too far gone to return Désiré's ardour; and our hero soon begins to suspect he might not be the only one in Winterlight who's acting a part.
