BMW has commissioned four audio books/podcasts — downloadable stories in .MP3 format — that include, somewhere in the plot, a BMW.
The four stories are by Karin Slaughter (crime writer published in 23 languages), (Shamus winner) Don Winslow, James Flint, and Simon Kernick (shortlisted for a CWA Ian Fleming Steel Dagger for best thriller 2005).
Enjoy!
