In September 1940, as Britain faced an imminent Nazi invasion, handpicked groups of ordinary men – known as scallywags – were trained in top secret to act as saboteurs and assassins. In a new series of wartime thrillers, author V.M. Knox has created the character of vicar Clement Wisdom, called upon to lead a local team of scallywags, creating a tension between his faith and his patriotic duty. V.M. Knox talks to Rob Weinberg about her novels, in which historical fact meets crime fiction and the murky world of espionage.   See acast.com/privacy for privacy and opt-out information.
