An Impartial Witness by Charles Todd

I really enjoy this series, featuring a nurse usually on the WW2 front lines in France trying to save lives. However, whenever a murder takes place she succumbs to her abundant compassion, curiosity, and sense of justice that drives her into solving the mystery. Much of the action takes place back in England, where her family lives so the historical context includes not just a war zone, but also the Homefront where ordinary citizens are struggling with the resource shortages of a war economy, but also the frightening consequences of enemy bombings. Recommended.
