Agaton Sax faces one of his most challenging cases yet, when a secretive criminal mastermind steals Scotland Yard's 'register of current criminals' from under the nose of Inspector Joshua Lispington. Agaton will have to employ all of his considerable skill and intellect to get it back, overcoming fake detectives, masked men, incompetent sailors and even dastardly pirates! It's all just another day in the exciting life of Sweden's finest 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 in audio format, newly translated for the next generation and expertly narrated by Barnaby Eaton-Jones.
