Book four in 'The Old Gatehouse' series is set in the middle of the nineteen-twenties, and as usual, there's plenty on the go for Lord Barnes and his family as modernisation comes to Caiston Manor Estate. A train robbery takes place nearby, ensuring frequent visits to the Manor from Inspector Jakes, who also brings disturbing news of an old acquaintance. Michael shoulders greater responsibilities on the family estate and his wife, Lucy, helps avert a family rift. As for the younger generation, Anthony and his friend, Oscar, find plenty of opportunity during their holidays from the cathedral to enjoy adventure, football and culinary indulgence, whilst poor Primrose suffers a severe attack of measles, though gains a loyal and trusty friend to help her through. There's trouble aplenty when the story moves to Fenland, but Uncle Bertram's knowledge of the atmospheric West Fen proves especially useful to Michael's friend, Max, helping him get to grips with a flurry of forged banknotes. Almost all the usual 'team' put in an appearance in the course of the story, which unfolds in a mixture of cream cakes and crime.
