Page "The Spy Who Came in from the Cold" Paragraph 3

In Call for the Dead, Le Carré's debut novel, a key character is Hans-Dieter Mundt ( nicknamed " Blondie "), an assassin of the Abteilung, the East German Secret Service, who is working under diplomatic cover in London when uncovered by Circus agents George Smiley and Peter Guillam.

When discovered, he escapes from England to East Germany before Smiley and Guillam can catch him.

Two years later, at the time of The Spy Who Came in from the Cold, Mundt has risen from the field to the upper-echelon of the Abteilung, because of his successful counter-intelligence operations against the spy networks of the British Secret Service.
