Bridge players are a strange, obsessed bunch. So, at least, think the fruit bats that hang upside down in the mango trees outside Mango Bridge Club, observing with incredulity as the seniors stare at bits of cardboard and appear to derive from this activity their own peculiar brand of grim pleasure. No wonder. The bridge club is their life. It is the reason they get up in the morning, the reason they go to bed without despair.

But the elderly members soon find their beloved club under attack from destructive forces both within and without. The warring committee is bent on achieving absolutely nothing, and the club faces an existential threat from a dodgy shire councillor and his allies - a professor of sexology with a keen interest in ostrich sexual discourses, and a misogynistic erotic robot inventor with a depressed goldfish.

Add to the mix the odd explosive bridge player not too happy with partner’s play, a badly behaved octogenarian, and a romance between the unpopular club president and a beautiful newcomer to the town, and the members of Mango Bridge Club find themselves with dilemmas fit only for super sleuth bridge players.
