Working in office of the French king, jump to it! (9)

I believe the answer is:

deskbound

'working in office' is the definition.
(deskbound describes someone working at a desk)

'of the french king jump to it' is the wordplay.
'of the french' becomes 'des'.
'king' becomes 'k' (abbreviation for king in chess).
'jump' becomes 'bound' (bounding is a kind of jumping).
'to it' is a charade indicator (letters next to each other).
'des'+'k'+'bound'='DESKBOUND'

(Another definition for deskbound that I've seen is " Tied to sedentary work".)

I've seen this clue in The Times.
