This volume contains the collected stories of the Baker Street Irregulars, a group of London street urchins hired by the great detective Sherlock Holmes to aid him with his investigations. Famed for being able to hear all the streets have to tell and described by Holmes as “The Baker Street division of the detective police force”, the boys, led by their leader, Wiggins, collect vital information from the underbelly of Victorian London. Contents include: 'A Study in Scarlet' (1887), The Sign of Four' (1890), and 'The Crooked Man' (1893). A must-read for anyone who is a fan of Doyle's famous detective novels or the BBC series 'The Irregulars'. Arthur Conan Doyle (1859 - 1930) was a British writer, famous for his character 'Sherlock Holmes'. Whilst studying medicine at the University of Edinburgh, Doyle began writing short stories, and his first piece was published before he was 20. In 1887, Conan Doyle's first significant work, 'A Study in Scarlet', appeared in Beeton's Christmas Annual. It featured the first appearance of the detective Sherlock Holmes. A prolific writer, Conan Doyle continued to produce a range of fictional works over the following years and is still being referenced today.
