The Monster with 21 Faces (かい人21面相) was a name used as an alias by the person or group responsible for the blackmail letters in the Glico Morinaga case in Japan. The Monster with 21 Faces sent its first letter on May 10, 1984, to the giant food company Ezaki Glico following the kidnapping and escape of Katsuhisa Ezaki, president of Glico. The letter stated it had laced the company's confections with potassium cyanide soda, and it later threatened to put them on store shelves. None of these poisoned candies was found, but Glico products were removed from stores, resulting in a loss of more than $21 million and the laying off of 450 part-time workers. Meanwhile, the Monster with 21 Faces also sent letters to the media, taunting police efforts to capture the culprit(s) behind the scare.
