Imperial Scandal

Husband-and-wife British spies investigate a murder in Brussels amid a whirlwind of war and revelry in this “superb” Regency-era mystery (Historical Novel Society).
 
Removed to glamorous Brussels in the wake of Napoleon’s escape from Elba, intelligence agent Malcolm Rannoch and his wife, Suzanne, warily partake in the country’s pleasures—lush, bucolic afternoons followed by nights filled with lavish balls. But with the Congress of Vienna in chaos and the Duke of Wellington preparing for battle, the festivities are cut short when Malcolm is sent on a perilous mission that unravels a murderous world of espionage.
 
No one knows what the demure and respectable Lady Julia Ashton was doing at the château where Malcolm and a fellow British spy were ambushed. But now her enigmatic life has been ended by an equally mysterious death. And as the conflict with Napoleon marches toward Waterloo, and Brussels surrenders to bedlam, Suzanne and Malcolm will be plunged into the search for the truth—revealing an intricate labyrinth of sinister secrets and betrayal in which no one can be trusted . . .
