Lots in police department recalled as enterprising (7)
I believe the answer is:
dynamic
'enterprising' is the definition.
(thesaurus)
'lots in police department recalled' is the wordplay.
'lots' becomes 'many' (many means lots of something).
'in' means one lot of letters goes inside another.
'police department' becomes 'CID' (abbreviation for Criminal Investigation Department).
'recalled' says the letters should be written backwards (to recall can mean to bring something back).
'many' put within 'cid' is 'cimanyd'.
'cimanyd' in reverse letter order is 'DYNAMIC'.
'as' acts as a link.
(Other definitions for dynamic that I've seen before include "Energetic, with great force of character" , "Vigorous and effective" , "I'm Candy (anag) - full of beans" , "High-powered" , "Full of energy and ideas" .)
