Query: Deon Meyer has a Formula that Works

Deon Meyer entertains you with more than his excellent plots. He also introduces you to characters that you hope like hell he will be carrying forward to future novels. This particular book was fairly political, largely based on events that took place during the last days of Apartheid in South Africa. Well written and informative for anyone not familiar with South Africa.
