Troublesome child in predicament? (6)
I believe the answer is:
pickle
I believe this clue is a double definition.
'troublesome child' is the first definition.
(I've seen this before)
'predicament?' is the second definition.
(I've seen this in another clue)
'in' acts as a link.
(Other definitions for pickle that I've seen before include "Chutney, relish, salsa etc" , "A preserve or an informal predicament" , "Preserve in brine or vinegar" , "tricky spot" , "Steep - predicament" .)
