A man is found dead in his house, he was poisoned. The main suspect is his wife. But she has a cast-iron alibi and was far away when the poisoning happened. Nevertheless, the Tokyo police detectives Kusanagi and Utsumi – together with their friend Yukawa, a physics professor – try to figure out how she could have killed her husband without being on site.
Salvation of a Saint is an unusual crime novel insofar as its focus is more on "how was the crime done" than on "who had done it", with a cleverly constructed case of an (almost) perfect crime. Unfortunately, this leads to a very slow moving story, without any action or suspense, that I found rather boring.
