Salvation of a Saint by Keigo Higashino is a crime thriller first published in Japanese in 2008; later in 2012 it was translated into English. The novel is based on a famous detective Galileo. He has been featured in the previous book The Devotion of Suspect X as well.
As the novel opens, Yoshitaka Mashiba is found dead and the reason for his death was poison in his cup of coffee. Yoshitaka Mashiba was murdered just before leaving his marriage and his wife Ayane Mashiba, who was miles away from the crime scene. The obvious suspect is she – his wife Ayane – but the Police Detective Kusanagi does not believe this. He intends to find more; he assumes there is someone else. On the other hand, his junior Utsumi has gut feeling that the killer is Ayane. This is the time when Utsumi feels stuck and she calls her favourite professor Manabu Yukawa, also famous as Detective Galileo. Soon it becomes clear ‘Who and Why’ about the murder but ‘How’ is the rest of the narration.
The involvement of the Physics professor Manabu Yukawa aka Detective Galileo to solve the murder mystery makes the book even more interesting. He thinks it was an impossible murder and a perfect crime until he discovers the trick how the murder could have been committed.

You'll need to get hot cups of coffee for this book as coffee was the most important factor of this story. Yoshitaka Mashiba who intended to divorce his wife Ayane Mashiba as she's unable to conceive within the given time of their arrangement was found dead after drinking the arsenic-contained coffee.

Even after knowing the murderer, readers couldn’t heap the temerity to put it down, such is its magnificence.
