Keep a French bank official, one looking ahead (7-6)
I believe the answer is:
fortune-teller
'one looking ahead' is the definition.
(person looking into the future)
'keep a french bank official' is the wordplay.
'keep' becomes 'fort' (I've seen this before).
'a french' becomes 'une' ('a' in French).
'bank official' becomes 'teller'.
'fort'+'une'+'teller'='FORTUNE-TELLER'
(Other definitions for fortune-teller that I've seen before include "Clairvoyant, future diviner" , "Foreteller of destinies" , "one could predict a lot" , "Soothsayer" , "Palm reader" .)
