Kurosawa had meanwhile instructed Toho to purchase the film rights to "King's Ransom", a novel about a kidnapping written by American author and screenwriter Evan Hunter, under his pseudonym of Ed McBain, as one of his 87th Precinct series of crime books. The director intended to create a work condemning kidnapping, which he considered one of the very worst crimes. The suspense film, titled "High and Low", was shot during the latter half of 1962 and released in March 1963. It broke Kurosawa's box office record (the third film in a row to do so), became the highest grossing Japanese film of the year, and won glowing reviews. However, his triumph was somewhat tarnished when, ironically, the film was blamed for a wave of kidnappings which occurred in Japan about this time (he himself received kidnapping threats directed at his young daughter, Kazuko). "High and Low" is considered by many commentators to be among the director's strongest works.
