A story where nothing major happens for most of the plot. This could have been better if given the plot, Deighton could have made it more intense.
Anyways, I read this quite a while ago and the only thing I remember about it is that I was bored most of the time while reading it. But as it was written by Len Deighton, I persisted. I wouldn't say I was happy with the book in the end, but it was not that bad either.
But read this only if you have more time on your hands.
