<jats:p>This study explores how English is taught through literary texts, using Arthur Conan Doyle’s The Adventure of the Beryl Coronet as the main resource. The approach focuses on teaching advanced vocabulary and enhancing learners’ reading skills. A set of challenging words is selected from the story and is used in tasks such as paraphrasing, matching words with definitions, and gap filling. Moreover, if learners do not understand how to pronounce certain words, audio support is provided. The chosen vocabulary is also compared in its use then and now, so that changes in meaning are clearly understood. The study further aims to examine the methodological potential of detective fiction, to analyze how narrative structure supports comprehension, and to highlight the value of authentic linguistic input in vocabulary learning. It also considers key findings from previous research, which emphasizes that literary texts strengthen lexical retention through context. As a result, the results demonstrate that words are taught through consistent exposure, active practice, and contextual analysis. In conclusion, the article contributes to teaching English advanced words and enhancing reading skills through literary texts.          </jats:p>
