Eye of the Needle by Ken Follett

Eye of the Needle was a novel that catapulted Ken Follett to instant fame. It was first published in 1978 with the title of 'Storm Island', and eventually became much more successful as 'Eye of the Needle'. It was the author's first major success and set him up to write many more successful novels based on a fast action track incorporating a spy thriller.
The novel takes a historical period (not too far back though - World War 2) and spins a story around that. The concept of a ice-cold anti-hero all out to break the secrecy of the allied effort getting felled by the courage of a lady with whom he has had an affair was very gripping. The story line is not very complex, but there is a fair amount of detail that holds the reader.



During World War II, the allied forced had been pushed from Europe and needed to re-enter the continent in order to take on the Nazis militarily. There are not too many feasible invasion routes, with the Dover-Calais route being the shortest and hence the most likely. The allies had however decided to take the longer Normandy landing; the biggest question was about how to protect this information from the Germans and to get them to focus on the Calais entry point. This entire operation was called Operation Fortitude, and it involved setting up a massive fake army so that the Germans could be deceived from afar. However, if a spy on the ground looked, he would be able to determine that this entire operation was a fake.
And the novel is based on such a person. A skilled spy, called 'Die Nadel', who is ice-cold and can kill anybody if they get in his way, eventually finds out the extent of the fake army and has to reach his submarine pick-up in a remote corner of Britain, and also transmit his findings to the German high command.
And then he runs into this couple living on an isolated island. A young couple, but the husband got crippled in an accident and is now very bitter, with the bitterness causing their relations to drift apart. And into this comes the spy; the inevitable happens; he soon starts to have an affair with the wife (the entire scenario described in some detail). At the same time, Der Niedle is being hunted by the British military who have found out about him and will do anything to hunt him down and kill him.
So what happens ? Does the husband find out about him ? Will the cold spy be able to reveal his truth or will he be found ? What about the affair between the wife and him ? 'Eye of the needle' is a well paced thriller with some well sketched out characters.
