In this Grave Hour (The Maisie Dobbs Mystery series Book 13)

Britain is at war. Returned from a dangerous mission onto enemy soil and having encountered an old enemy and the Fuhrer himself along the way, Maisie Dobbs is fully aware of the gravity of the current situation and how her world is on the cusp of great change. One of those changes can be seen in the floods of refugees that are arriving in Britain, desperate for sanctuary from the approaching storm of war. When Maisie stumbles on the deaths of refugees who may have been more than ordinary people, she is drawn into an investigation that requires all her insight and strength.
