Fear of being caught? (12)
I believe the answer is:
apprehension
I believe this is a double definition.
'fear' is the first definition.
(I know that apprehension is a type of fear)
'being caught?' is the second definition.
(being caught or apprehended)
'of' acts as a link.
(Other definitions for apprehension that I've seen before include "Fearful anticipation" , "Fear" , "Anxious anticipation; understanding" , "Arrest -- dread" , "Trepidation" .)
