"Not far from the sprawling grounds of Wyndham Hall, the body of longtime MI6 agent John Repton is found, shot dead with a single bullet to the heart. The corpse’s proximity to the estate sends ripples of concern through the intelligence community: Repton was killed while surveilling the members of a household with alleged ties to fascists who threaten the security of the country, as Hitler’s influence spreads across Europe. Elena Standish is assigned the case, thanks to her new connection to the Wyndham family: Her older sister, Margot, is being courted by Lady Wyndham’s brother."
