Collins brings the Queen of Crime, Agatha Christie, to English language learners. Agatha Christie is the most widely published author of all time and in any language. Now Collins has adapted her famous detective novels for English language learners. These carefully adapted versions are shorter with the language targeted at upper-intermediate learners (CEF level B2). Each reader includes: * A CD with a reading of the adapted story * Helpful notes on characters * Cultural and historical notes relevant to the plot * A glossary of the more difficult words There is a dangerous atmosphere at Stoneygates, a centre for young criminals. When Miss Marple visits her friend there, she can sense the danger, too. One evening during her stay someone shoots at the administrator of the centre. He is not injured, but a visiting relative is shot dead at the same time in another part of the building. Could this be a coincidence? Miss Marple must solve the mystery.
