This is a mind-bending murder mystery where theory clashes with reality and facts clash with instincts. 
Yoshitake was about to leave his marriage and his wife. But he was found dead in his home, and the cause was poison in his coffee. The logical suspect is his wife, Ayane. But she was hundreds of miles away when he was murdered.

Lead detective Kusunagi refuses to doubt the wife. But his assistant, Utsumi, can’t help but suspect the wife. As the facts clash with her logical assumptions, she decides to seek help from Professor Manabu, known as Detective Galelio. But even Manabu is having a hard time with this case. Nothing is as it seems. However, he must figure it out and catch this dangerous killer. This is a story that keeps the reader questioning themselves and includes plot twists that no one sees coming. An entertaining book to keep one on the edge of their seat the whole time.
