This is an entertaining story but also a good description of Cold War era.
It's not the best Appleby and the mystery was a bit underdeveloped but it was highly entertaining because Innes developed some quirky and interesting characters that I loved.
Plenty of humor and ducks, a couple of twins, Judith Appleby investigating.
I found it engrossing and had a lot of fun, recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
