|| Now physics professor Manabu Yukawa, Detective Galileo, returns in a new case of impossible murder, where instincts clash with facts and theory with reality. When a man, who was about to leave his marriage, is poisoned to death, his wife becomes the logical suspect. Except for one simple fact. She was hundreds of miles away when he was murdered, apparently incapable of lacing the coffee with the poison that killed him. Tokyo Police Detective Kusanagi and his assistant , Kaoru Utsumi, cannot agree on a suspect. Was it his wife, his girlfriend, his business associate? When they call upon their secret weapon, Professor Manabu Yukawa, even his brilliant mind is challenged by a crime that is implausible, methodical and perfect.
