She’s caught in a deceit (5)
I believe the answer is:
alice
'she's' is the definition.
'caught in a deceit' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'in' indicates putting letters inside.
'deceit' becomes 'lie' (I've seen this in other clues).
'a'+'lie'='alie'
'c' going into 'alie' is 'ALICE'.
(Other definitions for alice that I've seen before include "Girl famous for entering Wonderland" , "Girl who famously explored Wonderland" , "Lewis Carroll character" , "Celia changes into a different girl" , "Movement" .)
