Probably the most famous of John LeCarre’s work is the Karla Trilogy, which began with this novel. It was adapted for film originally by the BBC in 1979 as a 7 part miniseries starring Sir Alec Guiness. For those who read the novels, there is some difference in the order in which the material is presented from the novels. Right off the bat, we begin with Control’s conversation with Jim Prideaux concerning the code names he’d worked out for his suspicion of a mole residing at the top of the Circus. In the novel, our story begins with Peter Guillam breaking into George Smiley’s House and taking him to see Oliver Lacon. Lacon, the same man who had fired him only 18 months prior, needs George to investigate the possibility of a mole in the Circus when the reality of that possibility becomes more pronounced.
