Criminal stole a car — it gets things moving (9)
I believe the answer is:
escalator
'it gets things moving' is the definition.
(an escalator is a moving staircase)
'criminal stole a car' is the wordplay.
'criminal' is an anagram indicator.
'stole'+'a'+'car'='stoleacar'
'stoleacar' is an anagram of 'ESCALATOR'.
(Other definitions for escalator that I've seen before include "Carol eats (anag.)" , "Lift" , "Moving stairs" , "Moving stairway" , "the easy way up" .)
