In honour of Augustus’s underground activities, if you like Napoleonic era spies, you’ll probably like….
— Joanna Bourne’s The Spymaster’s Lady, which does a wonderful job showing us the perspective of a French agent;
— Tracy Grant’s Charles & Melanie books, Beneath a Silent Moon and Secrets of a Lady, and her more recent Suzanne & Malcolm books, Vienna Waltz and Imperial Scandal, all featuring a husband and wife spy team with sometimes conflicting loyalties;
— Julia Quinn’s To Catch an Heiress, which features some great comic spying;
— anything with Bernard Cornwell’s Richard Sharpe
in it (although Sharpe may not spy himself, he certainly encounters quite a few during his time in the Peninsula);
— and, of course, that demmed elusive Pimpernel.
