An air of treason

After his hair-raising adventures in London, Sir Robert Carey has finally tracked down Queen Elizabeth, who is about to make a state visit to Oxford. But instead of giving the Courtier his much-needed warrant and fee for being Deputy Warden of the West March with Scotland, Her Majesty orders him to investigate the most dangerous cold case of her reign - the mysterious 1560 death of Amy Dudley (nee Robsart), unloved wife of Robert Dudley, Earl of Leicester. Some thirty back, the late Dudley was Elizabeth's favorite suitor and potential husband. Amy died at Cumnor Place, close at hand. The Queen has since been one of the most obvious suspects in arranging Amy's murder. This makes Carey deeply uneasy with his sleuthing role. He's further uneasy that his father, Elizabeth's cousin from the wrong side of the of the blanket, is clearly involved. Then someone manages to poison Carey with belladonna, which temporarily blinds him. Worse still, Sergeant Dodd, the man most often guarding Carey's back, has disappeared on the road from London. As the Queen's scandalous past collides with her magnificent State entrance into Oxford, can Carey rally in time to find both Dodd and the true murderer of Amy Robsart?
