Amateur sleuth Queen Elizabeth II is back on the case in 1960s England in the fifth installment of this historical mystery series the New York Times Book Review calls “sheer entertainment,” perfect for fans of Rhys Bowen and Richard Osman.

1961, England.
The Queen is spending a night on board the royal train with her entourage and her sister, Princess Margaret. But before they reach their destination, an unreliable witness claims to have seen a brutal murder from one of the carriages.

The Queen and her assistant private secretary, Joan McGraw, get to work on their second joint investigation. No one else saw the crime. If there is a victim, could he be the missing photographer friend of Margaret’s new husband, Tony Armstrong Jones?

This time, the Cold War threatens to undermine the Queen’s upcoming visit to Italy. She and Joan must tackle dark forces that follow them all the way, in a tale of spies, lies, and treachery. 

This charming mystery will be perfect for fans of The Crown and Miss Marple.
