Lawyer brings Anne back, leaving the north, using river in Mexico - that's the setting (8)
I believe the answer is:
scenario
'setting' is the definition.
(I know that scenario is a type of setting)
'lawyer brings anne back leaving the north using river in mexico that's' is the wordplay.
I cannot quite see how this works, but
'north' could be 'n' (abbreviation) and 'n' is present in the answer.
'river' could be 'ea' (I've seen this in other clues) and 'ea' is present in the remaining letters.
'that's' could be 'sc' (short for Latin scilicet- 'it follows' or 'that is) and 'sc' is found within the answer.
The remaining letters 'rio' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'the' is the link.
Can you help me to learn more?
(Other definitions for scenario that I've seen before include "Film script outline" , "Film/novel plot outline" , "Outline -- setting for a novel" , "expected sequence of events" , "Envisaged situation" .)
