The Devotion of Suspect X

Yasuko Hanaoka, a single mother working at a bento shop in Tokyo, finds her quiet life violently disrupted when her abusive ex-husband, Shinji Togashi, reappears and threatens her and her daughter, Misato. In a desperate act of self-defense, they accidentally kill him. Their seemingly hopeless situation takes a startling turn when Yasuko's reclusive, brilliant neighbor, the high school math teacher Ishigami, offers to help them cover up the crime. Ishigami meticulously crafts a foolproof alibi, creating a complex web of deception that appears impenetrable. As Detective Kusanagi and his physics professor consultant, Dr. Manabu Yukawa (known as Detective Galileo), delve into the baffling case, they are confronted by a crime scene that defies conventional logic. Yukawa, a former university classmate of Ishigami, soon realizes he's up against a formidable intellect, and the investigation transforms into a thrilling battle of wits between two geniuses, with Yasuko's fate hanging precariously in the balance.
