Adventurous girl caught in a lie (5)
I believe the answer is:
alice
'adventurous girl' is the definition.
(main character in Alice's Adventures in Wonderland)
'caught in a lie' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'in' is an insertion indicator.
'a'+'lie'='alie'
'c' inserted inside 'alie' is 'ALICE'.
(Other definitions for alice that I've seen before include "woman" , "Girl in literary Wonderland" , "Wondergirl" , "Girl famous for entering Wonderland" , "Carroll heroine" .)
