Directed by Kiyoshi Kurosawa
An involving story of an apparent series of copycat murders, this film focuses on the detective hero and his mentally wife. Discarding the supposition that the similar murders by different killers are inspired by movies or television, the detective doggedly pursues his outlandish hunch and discovers the truth behind the killings that is pausible and shocking.
Recently featured on the Sundance Channel, this film resurfaces there occasionally and is worth scanning the schedules for.
