What type of publication does Len Deighton and Margaret Landon have in common?
Len Deighton Leonard Cyril Deighton ( ; born 18 February 1929), known as Len Deighton, is a British author. Deighton is considered one of the top three spy novelists of his time (along with Ian Fleming and John le Carré). In addition he is a highly acclaimed military historian, cookery writer, and graphic artist. "The IPCRESS File" (1962), his first novel, was an instant bestseller and broke the mould of thriller writing. "The Sunday Times" called him "the poet of the spy story". Deighton’s first protagonist – a nameless spy christened Harry Palmer in the films – was made famous worldwide in 1960s films starring Michael Caine.
Noel Streatfeild Mary Noel Streatfeild OBE (24 December 1895 –11 September 1986), was an English author, best known for children's books including the "Shoes" books, which were not a series. Random House, the U.S. publisher of the 1936 "Ballet Shoes" (1936), published some of Streatfeild's subsequent children's books using the word "Shoes" in their titles, to capitalize on the popularity of Ballet Shoes; thus "Circus Shoes", "Party Shoes" (in Britain, "Party Frock"). She won the third annual Carnegie Medal for "The Circus Is Coming", also published as "Circus Shoes". She was a member of the historic Streatfeild family.
