Monster with 21 Faces

In 1984, the president of Glico, a major Japanese candy company, was kidnapped from his home by masked men. He escaped, but the nightmare was just beginning. A group calling themselves "The Monster with 21 Faces" began sending mocking letters to the police and media, threatening to poison the companys candy on store shelves with cyanide.
This book investigates one of the most bizarre unsolved crimes in history. The criminals didnt just want money; they wanted chaos. They taunted the police ("Dear stupid police officers..."), gave clues that led nowhere, and successfully forced recalls that cost millions. The "Fox-Eyed Man," a prime suspect, was spotted multiple times but never caught.
"The Monster with 21 Faces" explores the cultural impact of the case, which led to the suicide of a police superintendent out of shame. After months of terrorizing multiple food companies, the group simply announced they were bored and would stop harassment. They vanished forever, leaving a nation gripped by paranoia about what was inside their snacks.
