Surveillance job with second coffee option provides clue to theme (5-3)
I believe the answer is:
stake-out
'surveillance job' is the definition.
(a stake-out is a surveillance operation)
'second coffee option provides clue to theme' is the wordplay.
I cannot quite understand how this works, but
'second' could be 's' (common abbreviation) and 's' is located in the answer.
'coffee option' could be 'takeout' (coffee might be ordered as take out or takeaway) and 'takeout' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'with' acts as a link.
(Another definition for stake-out that I've seen is " Police surveillance operation".)
