In This Grave Hour, by Jacqueline Winspear. Maisie Dobbs #13. Britain is now at war, and Maisie is investigating the deaths of various Belgian men who had been refugees during the first war, and people connected with them. Not a particularly strong book in the series - it's unclear why the murderer also kills the women (he has no grievance with them), and it's also unclear why Maisie is being discouraged from adopting a particular little girl - presumably a wealthy widow with a strong social network would be an adequate mother?
