Agaton Sax and the Diamond ThievesPaperback, 17 March 2022

When a world-renowned artist approaches Agaton Sax and asks to have his daily illustrations featured in the Byköping Post (the world's smallest newspaper, but also the best) the detective's interest is piqued. Could the detailed patterns and swirls within the pictures hide a secret code? Maybe they will lead to a nefarious plot for Agaton to foil...

But is a 113-year-old man really behind it all? And will Sweden's greatest crimefighter get an opportunity to put an old acquaintance back behind bars where he belongs? It's yet another fascinating case for the one and only Agaton Sax!

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.
