Book Log 2022 #35: The English Assassin by Daniel Silva

Art restorer and Israeli spy Gabriel Allon is in Switzerland for his former job, only to find that the owner of the Raphael he's restoring has been killed - and left at the foot of the painting. An investigation uncovers that the owner also held a collection of looted Impressionist paintings, which are now gone. Allon is tasked by his service to track down the killer (who appears to be someone Allon trained) and recover the art so it can be returned to its rightful owners.

This book has all the hallmarks of the spy thriller - twisty plot, gunplay, clandestine meetings, etc. - while throwing some light on how Switzerland became a repository for treasure stolen by Nazi Germany. I enjoyed the book quite a bit and will likely stick with this series.
