In the summer of 1932, Maisie Dobbs’ career goes in an exciting new direction when she accepts an undercover assignment directed by Scotland Yard’s Special Branch and the Secret Service. Posing as a junior lecturer, she is sent to a private college in Cambridge to monitor any activities “not in the interests of His Majesty’s Government.”

When the college’s controversial pacifist founder and principal, Greville Liddicote, is murdered, Maisie is directed to stand back as Detective Chief Superintendent Robert MacFarlane and Detective Chief Inspector Stratton spearhead the investigation. She soon discovers, however, that the circumstances of Liddicote’s death appear inextricably linked to the suspicious comings and goings of faculty and students under her surveillance.

To unravel this web, Maisie must overcome a reluctant Secret Service, discover shameful hidden truths about Britain’s conduct during the war, and face off against the rising powers of the Nationalsozialistische Deutsche Arbeiterpartei—the Nazi Party—in Britain.

A pivotal chapter in the life of Maisie Dobbs, A Lesson In Secrets marks the beginning of her intelligence work for the Crown. As the storm clouds of World War II gather on the horizon, Maisie will confront new challenges and new enemies—and will engage new readers and loyal fans of this bestselling mystery series.
