Uncle Fred, or to give him his full title: Fredrick Altamont Cornwallis Twistleton, fifth Earl of Ickenham, is considered by some as a "splendid gentleman, a sportsman to his fingertips". Mr Twistleton, nephew to Earl, and otherwise known as "Pongo" to his friends, has a differing view. He simply describes his uncle as "being loopy to the tonsils". But when the eccentric and well-loved Uncle Fred plays Cupid to Lord Emsworth, his old friend at Blandings Castle, little did he know that he would be known as Impostor A and the Lord's beloved pig, the Empress, as Impostor B.
