An enjoyable book but I did find it rather slow at the beginning hence the reason I've rated it as 4 star. It did however pick up pace and was very good further in. I have now read all of the series and enjoyed them all
I bought the first one because it was free on the kindle and was immediately hooked. Have since bought the whole series and am now reading number 6. WOuld recommend to anyone who likes a little spy and espionage adventure. I am now M H Sargents number 1 fan.
