They can bring out the detective in you (5)
I believe the answer is:
clues
'they' is the definition.
Both the definition and answer are plural nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for clues that I've seen before include "Indications" , "Here, they're across and down" , "Hints (that you're looking at?)" , "Crossword aids" .)
