I enjoyed this which was a rollicking good read. It is the third in the series and it does help to have read the previous two as there are continuing characters. The plot is all developed and the book covers the confusing period immediately after the declaration war in 1939 where nobody is quite who they seem to be. There is a lot of derring-do and chases and red herrings but the historical background is sound and the story finally comes round to a satisfactory conclusion. Tom Wilde, the professor, is an interesting hero and Marcus Marfield a well-drawn sociopath. A good read and highly recommended.
