October 1942. Jo Hardy, an Air Transport Auxilliary ferry pilot, is delivering a Spitfire to Biggin Hill Aerodrome, when she has the terrifying experience of coming under fire from the ground. In a bid to find out who was trying to take down her aircraft, she returns on foot to the area, and discovers an African American soldier bound and gagged in an old barn. A few days later another ferry pilot crashes and is killed in the same area of Kent. Although the death has been attributed to 'pilot error' Jo believes there is a connection between all three events - and she wants desperately to help the soldier, who is now in the custody of American military police.Jo is advised to take her suspicions to Maisie Dobbs. As the psychologist-investigator delves into the case, she discovers the attempt to take down ferry pilots and the plight of the black American soldier are inextricably linked with the visit to Britain by the First Lady of the United States, Eleanor Roosevelt. Maisie must work with speed to uncover the depth of connection, to save the life of the president's wife and a soldier caught in the crosshairs of those who would see them both dead.
