Adapted from Sir Arthur Conan Doyle’s detective novel, Sherlock
became a hit at home and abroad due to its clever plot and unique character.
Based on Grice’s cooperative principle and conversational implicature theory,
this paper explores the wonderful dialogues in Sherlock and their pragmatic
connotations, aiming to help readers have a deeper understanding of the
development of the plot, a profound meaning of the dialogues and to provide a
basis for benign communication.
