For the very first time, this eleventh Agaton Sax adventure is now available in English! Agaton Sax, Sweden's best detective, must decipher the mystery of a sticky-fingered thief whose calamitous crimes see him targeting a group of billionaires and their mountains of money. Flown on a private jet to a castle in England to catch our corrupt culprit, Agaton enlists the aid of his friend and colleague from Scotland Yard, Inspector Lispington. But can this duo discover who is behind the billionaires' bankruptcy? Or have the intrepid investigators finally met their match? 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.
