I'm unclear on how this has been achieved or if permissions have been given. Presumably, Audible (part of Amazon) have their own procedures to ensure legality, but here it is nonetheless;

The narrator is good although why he's presenting it as a podcast with each episode being one chapter rather than as a straight audiobook is beyond me.
Hopefully this is legit.
