Poor Ricki....
He never did get Irina back of course. It’s sad because he really liked her, maybe loved. Do you think when Smiley told him “I’ll do my utmost Ricki” that he knew beforehand that she was dead? Possibly from Prideaux? But Jim couldn’t have known who she was & it would be a stretch to say Smiley deduced who she was (if he was interested that is) from what Jim may have told him.
Just curious to see what you all think.
