Maisie Dobbs got her start as a maid in an aristocratic London household when she was thirteen. Her employer, suffragette Lady Rowan Compton, soon became her patron, taking the remarkably bright youngster under her wing. Lady Rowan’s friend, Maurice Blanche, often retained as an investigator by the European elite, recognized Maisie’s intuitive gifts. The outbreak of war changed everything. Ten years after the Armistice, in the spring of 1929, Maisie sets out on her own as a private investigator, one who has learned that coincidences are meaningful, and truth elusive.

London, 1940: Winston Churchill has just been sworn in, war rages across the Channel, and the threat of a Blitz looms larger by the day. But none of this deters Maggie Hope. She graduated at the top of her college class and possesses all the skills of the finest minds in British intelligence, but her gender qualifies her only to be the newest typist at No. 10 Downing Street. Her indefatigable spirit and gifts for codebreaking, though, rival those of even the highest men in government, and Maggie finds that working for the prime minister affords her a level of clearance she could never have imagined....

By July 1914, the ties between Kezia Marchant and Thea Brissenden, friends since girlhood, have become strained - by Thea's passionate embrace of women's suffrage, and by the imminent marriage of Kezia to Thea's brother, Tom, who runs the family farm. When Kezia and Tom wed, just a month before war is declared between Britain and Germany, Thea's gift to Kezia is a book on household management - a veiled criticism of the bride's prosaic life to come.

The daughter of a distinguished soldier, Bess Crawford follows in his patriotic footsteps, volunteering to serve her country as a nurse during the Great War.

When Bess arrives at the Graham house in Kent, Jonathan Graham listens to his brother's last wishes with surprising indifference.

Los Angeles, 1943. As the Allies beat back the Nazis in the Mediterranean and the United States military slowly closes in on Tokyo, Walt Disney cranks out wartime propaganda and the Cocoanut Grove is alive with jazz and swing every night. But behind this sunny façade lies a darker reality. Up in the lush foothills of Hollywood, a woman floats lifeless in the pool of one of California’s trendiest hotels. When Maggie Hope learns that this woman was engaged to her former fiancée, John Sterling, and that he suspects her death was no accident, intuition tells her he’s right.
