The Fifth Queen Trilogy by Ford Madox Ford. Ford Madox Ford's Fifth Queen Trilogy, telling the story of Katharine Howard at the court of Henry VIII, is considered by some to be his best work.

The Fifth Queen trilogy is a series of connected historical novels by English novelist Ford Madox Ford. It consists of three novels, The Fifth Queen; And How She Came to Court (1906), Privy Seal (1907) and The Fifth Queen Crowned (1908), which present a highly fictionalised account of Katharine Howard's arrival at the Court of Henry VIII, her eventual marriage to the king, and her death.

Katharine Howard is introduced in the first book as a devout Roman Catholic, impoverished, young noblewoman escorted by her fiery cousin Thomas Culpeper. By accident, she comes to the attention of the king, in a minor way at first, is helped to a position as a lady in waiting for the then bastard Lady Mary, Henry's eldest daughter, by her old Latin tutor Nicholas Udal. Udal is a spy for Thomas Cromwell, the Lord Privy Seal.
