The Saint: Five Complete Novels: The Man Who Was Clever, The Lawless Lady, The Saint Closes the Case, The Avenging Saint, The Saint vs. Scotland Yard

Simon Templar is a thief known as The Saint because of his initials (ST) and because his heroic exploits fly in the face of an otherwise nefarious reputation. Templar has aliases, often using the initials S.T. such as "Sebastian Tombs" or "Sugarman Treacle". His true name is unknown, and the name "Templar" was adopted at an early age from reading about the Poor Fellow-Soldiers of Christ and of the Temple of Solomon, the Knights Templar. Blessed with boyish humor, he makes humorous and off-putting remarks and leaves a "calling card" at his "crimes", a stick figure of a man with a halo, the logo of the books, the movies, and the 1960s TV series.
