His Grace, The Duke of Ankh, Commander Sir Samuel "Sam" Vimes is a fictional character in Terry Pratchett's Discworld series. Vimes is depicted in the novels as somewhere between an Inspector Morse-type 'old-school' British policeman, and a film noir-esque grizzled detective. His appearances throughout the Discworld sequence show him slowly and grudgingly rising through the ranks of both police force and society. As of his latest promotion, his full name and title is: "His Grace, His Excellency, The 1st Duke of Ankh; Commander Sir Samuel Vimes": When serving as Ambassador for Ankh-Morpork, he is also referred to simply as "His Excellency", and is also nicknamed "Blackboard Monitor Vimes", "Vimes the Butcher/Butcher Vimes" and "Vetinari's Terrier" : According to his wife, Sybil, Vimes is recognised by many as Lord Vetinari's right-hand man.
