Mark Frost has written some particularly well received books about golf, none of which I have read. Before he became known for those books he wrote two excellent thrillers called “The List of 7” and “The 6 Messiahs”. Recently I discovered that he had written a new fiction novel, this time set during World War II. On the basis of his past record I took the chance. After a slow start this is proving to be a cracking read.
