Emily's recast Le Carre's spy (6)

I believe the answer is:

smiley

I'm a little stuck... Click here to teach me more about this clue!

'spy' is the definition.
(John le Carre character George Smiley)

'emily's recast' is the wordplay.
'recast' indicates an anagram.
'emilys' with letters rearranged gives 'SMILEY'.

'le carre's' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for smiley that I've seen before include "Cheerful emoticon" , "Grinning face symbol" , "Spymaster" , "sounds cheerful" .)

I've seen this clue in The Sun.
