Busy Body (Agatha Raisin Series #21)

Agatha Raisin has always been ambivalent about holiday cheer, but her cozy little village of Carsely has long prided itself on its Christmas festivities. But this year Mr. John Sunday, a self-important officer with the Health and Safety Board, has ruled that the traditional tree on top of the church is a public menace; that lampposts are unsafe for hanging illuminations; that May Dimwoody's homemade toys are dangerous for children… Things have reached such a desperate pass that the Carsely Ladies' Society joins forces with the ladies in the neighboring village of Odley Cruesis to try to put a stop to Mr. Sunday's meddling—only to find that someone has literally put a stop to him with a kitchen knife.

Agatha's detective agency is on the case, but when a man has made as many enemies as John Sunday, it's hard to know where to start…
