The Smiler with the Knife (The Nigel Strangeways Mysteries Book 5)

A couple in the British countryside finds themselves fighting fascists in this suspenseful novel by “a master of detective fiction” (The Daily Telegraph).
 
In 1930s England, Nigel and Georgia Strangeways have settled into rural bliss, thinking their days of globe-trotting detective work are behind them—but little do they know a disturbing mystery is lurking in their own front yard. When a letter arrives commanding the couple to tend their hedges, the most menial of domestic duties propels the Strangeways out of their cozy life, and into the peril of a power-hungry plot.
 
With the help of Nigel’s uncle, Sir John Strangeways, they learn of a treasonous conspiracy bigger than their small town. To expose the sinister schemers, Georgia must risk her life and infiltrate a group of fascist sympathizers before they succeed in their plan to overthrow the government . . .
