The Comfort of Ghosts by Jacqueline Winspear

It's 1945 and World War II is over. With the death of Lord Julian Compton, Maisie is helping her former mother-in-law, Lady Rowan, settle Lord Julian's affairs. When squatters are discovered at the family's London mansion, Maisie lets the lawyers know she will look into the matter. Maisie's investigation leads her to protect some of the youngest people who worked for Britain in the war effort. In this final book of the Maisie Dobbs series, Winspear lets the reader visit with all the characters in Maisie's world one last time. The Comfort of Ghosts will be published in June.
