Frederick Knott

Frederick Major Paull Knott (28 August 1916 – 17 December 2002) was an English playwright and screenwriter known for his ingeniously complex, crime-related plots. Though he was a reluctant writer and completed only three plays in his career, two have become classics: the London-based stage thriller Dial M for Murder, which was later filmed in Hollywood by Alfred Hitchcock, and the chilling 1966 play Wait Until Dark, which also was adapted to a Hollywood film directed by Terence Young.
