Penguin Readers is an ELT graded reader series for learners of English as a foreign language. With carefully adapted text, new illustrations and language learning exercises, the print edition also includes instructions to access supporting material online.

Titles include popular classics, exciting contemporary fiction, and thought-provoking non-fiction, introducing language learners to bestselling authors and compelling content.

The eight levels of Penguin Readers follow the Common European Framework of Reference for language learning (CEFR). Exercises at the back of each Reader help language learners to practise grammar, vocabulary, and key exam skills. Before, during and after-reading questions test readers' story comprehension and develop vocabulary.

The Adventures of Sherlock Holmes, a Level 3 Reader, is A2 in the CEFR framework. The text is made up of sentences with up to three clauses, introducing first conditional, past continuous and present perfect simple for general experience. It is well supported by illustrations, which appear on most pages.

From finding a diamond in a bird's stomach, to stealing a racehorse - in these four stories, the famous detective Sherlock Holmes works with his friend Dr Watson. Holmes understands people and he finds many clues. But will he solve the crimes?
