When Peter Bennett is made redundant from his publishing company in the UK he decides he needs a break before starting on a new phase of his career. Influenced by his mother's life-long love of France he decides to accept a long-standing invitation to visit friends in South-West France or "Deepest France" as he likes to call it. But from the moment he sets foot on French soil nothing goes to plan and Peter rapidly finds himself involved in a series of intrigues as the fast-paced plot twists and turns like the deep mountain valley where the action takes place.
