Returning from a much-needed holiday, Persimmon 'Simmy' Brown discovers that life in the Lake District is, as ever, far from relaxing. Before she can enjoy the idea of being the future Mrs Chris Henderson, her fiancé discovers the body of his friend, antique dealer Jonathan Woolley, brutally strangled in a house in Grasmere. Enlisting the help of her friends and amateur detectives Ben and Bonnie, the investigation appears to ask more questions than it answers as historical grudges against the dead man are revealed. It seems that many people had a reason for wanting him dead.

When one of the lodgers at her parents’ B&B dies in her arms after seemingly being poisoned, she becomes embroiled in a complex investigation, headed up by her friend DI Moxon.

It is Sunday afternoon, and Theodosia and Drayton are catering a formal tea at a hot-air-balloon rally. But as the sky turns gray and the clouds start to boil up, a strange object zooms out of nowhere. It is a drone, and it appears to be buzzing around the balloons, checking them out. As Theodosia and Drayton watch, the drone, hovering like some angry, mechanized insect, deliberately crashes into the balloon next to them. An enormous, fiery explosion erupts, and everyone watches in horror as the balloon plummets to the earth, killing all three of its passengers.
