Frederick Knott

Frederick Knott was an English playwright and screenwriter known for complex crime-related plots. Although he was a reluctant writer and completed a small number of plays, two have become well-known: the London-based stage thriller "Dial M for Murder", later filmed in Hollywood by Alfred Hitchcock, and the 1966 play "Wait Until Dark", which was adapted to a Hollywood film directed by Terence Young. He also wrote the Broadway mystery "Write Me a Murder".
