Old William Faraday is dead, apparently of natural causes. Another man is dead too, and it was certainly murder. Mr Campion and his family are back in Pontisbright, along with Magersfontein Lugg and DCI Charles Luke. Danger is hardly unknown in this idyllic Suffolk village, but it is a less romantic peril than on Mr Campion's first visit, more than twenty years ago. Mr Campion's friends Minnie and Tonker Cassands put on a cheerful face as they prepare for their annual party at Minnie's house, The Beckoning Lady, but Minnie has serious problems with the Inland Revenue - and the dead man in the ditch is a tax inspector. Mr Campion has a formidable adversary in Superintendent Fred South of the Suffolk Police, whom we encountered in 'Safer than Love'. And to cap it all, Charlie Luke falls like a ton of bricks for the most unsuitable girl imaginable...
