I believe the answer is:

bond

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

'james's' is the definition.
(James Bond is a fictional spy)

I cannot understand how the remainder of the clue works.

(Other definitions for bond that I've seen before include "Tie - 007" , "Join; secret agent" , "relationship" , "Unite" , "Fastening; financial certificate" .)

I've seen this clue in the Evening Standard.
