Lewis employs careful language to hedge the title’s bold assertion.

Given the value, danger, and sheer flamboyance of Baker’s spying activities, it’s a shame that she hasn’t found a better chronicler of her exploits or her complicated history. For Agent Josephine, Damien Lewis, the British author of several works of military history and biography, dug into hard-to-access archives and the chronicles left by key players to create an account that is long on detail but sadly lacking in psychological insight or storytelling panache.

... much fresh detail.

Lewis provides a rollicking, energetic commentary on Baker’s adventures, noting her sangfroid in face of German interrogators and her boundless compassion for wounded soldiers and war victims. Lewis also reveals her quirky side, her bawdy humor, her spats with jealous fellow entertainers, and her ill-advised love affair with spy chief Jacques Abtey. Lewis’ biography is set to be adapted for a miniseries starring Janelle Monáe as the remarkably talented and courageous Agent Baker..

Mr. Lewis is a prolific author of wartime histories and novels. Agent Josephine is not a biography (there have been many) but a lengthy account of the war and her espionage work, interspersed with background material on her life.

An extensive, well-researched tribute to Baker’s bravery; will appeal to any fan of biographies of outstanding women..

... compelling.

Lewis writes with a flair for hard-boiled drama, sharing insights into the clandestine world of espionage and its nests of expert, aristocratic spymasters; hard-living, shrewd field agents; and debonair mafiosos with their hideous henchmen. The drama is balanced with lively details. Readers will delight in tales of Josephine with her entourage of animals, including a pet cheetah named Chiquita, and fall for a narrative that almost resembles a friends-to-lovers romance, were it not for the immense stakes and horrifying consequences of failure. Agent Josephine is a wonderful addition to the canon of World War II stories..

Lewis has constructed a lengthy biography of this remarkable woman. Agent Josephine is based on factual data concerning her espionage cohorts, and against the background of war, hatred, racial and religious bias. It stresses the contrast between the underprivileged child and the adult hero she would become --- largely because of her strong character and true grit..

Rather than crafting a conventional biography, Lewis concentrates on the wartime years, creating a heroic portrait of the selfless, brave, somewhat reckless, pioneering, unswervingly patriotic spy for the Allies who was active even before the Nazi occupation of Paris, where she lived and worked. In a suspenseful, serpentine narrative, the author piles on the detail about Britain’s Secret Intelligence Service in France, an agency that worked closely with the Deuxième Bureau, France’s counterespionage service.

... scintillating.
