Peter & Mary Have A Row

Peter and Mary have been together since their teens. Happily so, for the most part. But now, suddenly, something seems to have gone wrong. Is it serious? Is it nothing? Do they need help?

Maybe. Maybe not. Either way, they're going to get it - from friends, from family, from total strangers with an unhealthy interest in the problem-solving abilities of slugs. And with help like this, they'll be lucky to preserve their sanity, let alone their marriage . . .
