WWII, murder, spies, the blitz—everything you need for a great historical mystery. This was a hit on the historical level, but a miss at being a mystery. Rationing, family being called to active duty, air raids, etc., allowed the reader to become immersed in the setting. But, setting isn‘t enough. Predictable plot bogged down by long first person narrative. If a second book comes out I might give it a try, in hopes of something a bit better.
