The Comfort of Ghosts by Jacqueline Winspear

Psychologist and investigator Maisie Dobbs unravels a profound mystery from her past in a war-torn nation grappling with its future.

London, 1945: Four adolescent orphans with a dark wartime history are squatting in a vacant Belgravia mansion—the owners having fled London under heavy Luftwaffe bombing. Psychologist and Investigator Maisie Dobbs visits the mansion on behalf of the owners and discovers that a demobilized soldier, gravely ill and reeling from his experiences overseas, has taken shelter with the group.
Maisie’s quest to bring comfort to the youngsters and the ailing soldier brings to light a decades-old mystery concerning Maisie’s first husband, James Compton, who was killed while piloting an experimental fighter aircraft. As Maisie unravels the threads of her dead husband’s life, she is forced to examine her own painful past and question beliefs she has always accepted as true.

The award-winning Maisie Dobbs series has garnered hundreds of thousands of followers, readers drawn to a woman who is of her time, yet familiar in ours—and who inspires with her resilience and capacity for endurance. This final assignment of her own choosing not only opens a new future for Maisie and her family, but serves as a fascinating portrayal of the challenges facing the people of Britain at the close of the Second World War.
