This novel is considered by many to be the gold standard for espionage novels, and I feel this honour is well deserved.
Some may find the novel hard to get into, but this is primarily the way that Mr. Le Carré wrote as his goal (at least in my opinion) is to make the reader think about what they're reading. This is a typical writing standard for mysteries, and to a certain point some other genres as well, but compared to these genres doing so in an espionage novels is much rarer, and therefore many people are not used to this form of writing. Mr. Le Carré however excelled at this.
The story for those of you who do not know it revolves around the investigation of a mole that has been planted in British Secret Service by the Russians. The mole has been in place for sometime, and his existence just came to light. The person in charge of what I assume is actually MI-6 but it's called "The Circus" has discovered the existence of the mole but does not know who it is. This leads him to dispatch an agent to acquire this information, however the information he was to require was a plant itself. The plot develops from this premise but I don't want to give anymore away.
The characterization in this novel is excellent, as are the settings. This book is not the first to feature the character of George Smiley, but it is definitely one of the most well known ones.
There have been two movie adaptions made of this book the first from 1979 which starred Sir Alec Guinness as Smiley, and it is by far the best of the two, as it is the closest to the book and is actually a 5 hour miniseries. The second (from 2011) starred Gary Oldman as Smiley is only two hours long and while it has the same general gist as the book they had to leave out a lot of detail. Also, as is typical for Hollywood today they added bits that we're not really necessary to the story.
An excellent read, highly recommended.
