* {{Adorkable}}: Bunny, a baby-faced aspiring writer whose childish enthusiasm for capers and constant fretting about his "invisible" mustache are quite endearing.
* FairForItsDay: Hornung supported women's suffrage, and the female characters in the ''Raffles'' stories are (for the most part) capable, intelligent and strong-willed women, and some of them are successful in their careers.
* HoYay: The series is known for its incredibly high HoYay quotient.
* MagnificentBastard: Written as an answer to Literature/SherlockHolmes himself by Creator/{{Arthur Conan Doyle}}'s brother in law, [[TitleCharacter AJ Raffles]] is a charming GentlemanThief who frequently robs the wealthy members of Victorian high society, with a special emphasis on honorless 'new rich' types, one point even stealing a valuable artifact from a museum and gifting it to the Queen herself for the Diamond Jubilee. Cunning and charming, Raffles repeatedly pulls off heists while sticking to his own curious code of honor, his exploits chronicled by his loyal friend Bunny. Raffles is rarely at a loss and just as good at being a criminal as Holmes is at detective work.
* StrangledByTheRedString: "An Old Flame", also a PsychoExGirlfriend.
* TearJerker: [[spoiler:Raffles's death in the war and Bunny's reaction to it]].
* UnintentionalPeriodPiece: The books are chock-full of Victorian era trivia, mores and personalities, and the years the books take place in can normally be easily pinpointed by the observant reader. (It's 1891-1900).
* ValuesDissonance: The books have their share of anti-Semitic and racist remarks.
