This was the first book I read in this series and it won't be the last as I thoroughly enjoyed.
A mix of historical mystery and historical fiction told in a dual timeline with an interesting cast of characters and a well researched and vivid historical background.
The author is a good storyteller and the story kept me hooked and guessing.
Even if it's the 5th book in this series it can be read as a stand alone.
Recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
