This is the second book I read in this series and it's excellent. A gripping historical mystery full of twists and turns, it kept me hooked and entertained till the end.
The mystery is solid and full of twists and turns. It's whodunnit and a spy story at the same, exciting and solid.
The characters are fleshed out and Walter Hardcastle, Ernst Hardcastle's son, is a clever detective and I liked him.
The author is a good storyteller and he delivers a very entertaining story.
The historical background is vivid and well researched.
I read the author died in 2020 and I assume this will be the last book. I'm sad because Walter Hardcastle series had a lot of potential and it could have a become a favorite.
Highly recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
