The Sign of FourPaperback, 1 October 2019

Moonlight was streaming into the room, and it was bright with a vague and shifty radiance. Looking straight at me and suspended, as it were, in the air, for all beneath was in shadow, there hung a face... A mysterious letter, a missing father, stolen jewels and a man found dead in a locked room. Private detective Sherlock Holmes and his faithful companion Dr Watson have their work cut out in a case which takes them through the suburbs of south London, back in time to the forts and swamps of colonial India, and climaxes in a dramatic chase along the river Thames. Arthur Conan Doyle's 1890 novel is the famous detective's second case. This Collins Classroom Classics edition includes an introduction and glossary to support students, written by an experienced teacher.
