Agaton Sax returns to fight his biggest criminal plot yet!Upon receiving a mysterious telegram during breakfast, Agaton soon finds himself searching to uncover the enigma around it. But it's not just one criminal mastermind behind this confounding communique—it's a whole cabal of them! And when Agaton discovers that they have captured his friend and confidant Inspector Lispington, Sax must come to the rescue as well as put a stop to the dastardly devils and their pernicious master plan—one that may spell the end for Sweden's most famous detective!The Agaton Sax series of books were first published in Sweden, later being translated into English and printed with illustrations by much-loved artist Quentin Blake (perhaps best known for his work on the books of Roald Dahl). The English translations became immensely popular, achieving the status of the most re-issued mystery & detective series in the history of Nordic children's literature.Now, after many years out of print, Oak Tree Books is proud to publish the entire Agaton Sax series, newly translated and illustrated for the next generation. This new collection includes the eleventh book which has never before been released in English.
