Whitefish held by Francis Company (5)
I believe the answer is:
cisco
'whitefish' is the definition.
(cisco is a kind of whitefish)
'held by francis company' is the wordplay.
'held by' indicates the answer is hidden within the clue.
'CISCO' can be found hidden inside 'francis company'.
(Other definitions for cisco that I've seen before include "western kid?" , "Catch" , "Fish" .)
