I love George Bellairs' mysteries and I think this the best I read so far.
It's fast paced, with a complex plot full of twists and turns, and unputdownable.
Inspect Littlejohn is at his best and the cast of characters is well thought and interesting, each of them with secrets and something to hide.
The mystery is solid, full of twists and red herrings, and it kept me guessing til the last turn that came as a surprise.
This book aged well and the description of the historical background is interesting.
I look forward to reading the next Bellairs' book.
It was an excellent read, strongly recommended.
Many thanks to Agora Books and Netgalley for this ARC, all opinions are mine.
