Might suit, shortly, to go back and collect vehicle to get Cretan captive (6)
I believe the answer is:
icarus
'cretan captive' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'cretan' relates to this answer.
'might suit shortly to go back and collect vehicle' is the wordplay.
I cannot quite see how this works, but
'vehicle' could be 'car' (car is a kind of vehicle) and 'car' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'to get' is the link.
Can you help me to learn more?
(Other definitions for icarus that I've seen before include "His false wings melted" , "one on hazardous trip" , "Son of Daedalus whose wings melted fatally" , "In Greek legend, he flew too high and died" , "Failed flier" .)
