A Royal Threesome(2014)

Rhys Bowen

Now in one volume—the first three “charming and lighthearted” ( Kirkus Reviews ) Royal Spyness Mysteries from New York Times bestselling author Rhys Bowen, featuring the elegant, titled, and stony-broke sleuth Lady Georgiana Rannoch.
 
HER ROYAL SPYNESS

Georgie is forced to earn her keep as a housekeeper in London when the Queen summons her to spy on the playboy prince. But when a Frenchman winds up dead in Georgie’s bathtub, it’s her job to clear her very long family name.
 
A ROYAL PAIN

While entertaining a Bavarian princess at the Queen’s behest, Georgie finds herself investigating the rather more worrisome matter of the dead body in the bookshop, as well as her royal guest’s unwitting involvement in the communist party.
 
ROYAL FLUSH

After being saved from scandal by her on-again-but-mostly-off-again beau, Darcy O’Mara, Georgie is shipped home, where Queen Mary wants her to keep Wallis Simpson from seducing the Prince of Wales, and Scotland Yard wants her to stop one of the members of the shooting party at Balmoral from turning their sights from the quails to His Royal Highness.
