After an attempt to earn money as a society companion ends badly, Georgie is sent back to Scotland to avoid gossip. At Castle Rannoch she is told to keep Wallis Simpson away from the Prince of Wales and then recruited to observe a shooting party at Balmoral after warnings that the prince may be the target of an assassination.
Georgie must distinguish accidents from deliberate attacks while living among relatives, courtiers and guests who resent her questions. As the danger moves closer to the royal party, she and Darcy try to uncover the plot without revealing how vulnerable the future king has become.
