Stuart Craigie really knows how to write spy thrillers. I immensely enjoyed reading this book. The author has a no-nonsense approach to writing completely Call Which is adequate for the genre. He spins a fine yarn and the story gets more complex in the course of the book. Which is Exactly what we want to read.
The only real issue is indeed the protagonist Dramatically retires in the very end of the book Which probably Means There Will Be no further Mike Sanders novels. Which is a pity.
