Tom's drive to find a temporary partner? (6)
I believe the answer is:
cruise
I believe this clue is a double definition.
'tom's' is the first definition.
(Tom Cruise)
'drive to find a temporary partner?' is the second definition.
(Other definitions for cruise that I've seen before include "journey" , "Tom, say" , "Holiday at sea" , "Tour by ship" , "Sail around" .)
