Working at the double, circle in all directions unaided (2,4,3)
I believe the answer is:
on ones own
'unaided' is the definition.
'working at the double circle in all directions' is the wordplay.
'working' becomes 'on'.
'at the double' indicates the doubling of some letters.
'circle' becomes 'o' (**).
'in' is an insertion indicator.
'all directions' becomes 'eswn' (compass directions).
'on' doubled is 'onon'.
'o' put within 'eswn' is 'esown'.
'onon'+'esown'='ON ONES OWN'
(Other definitions for on ones own that I've seen before include "Helpless" , "Alone" , "Independently" .)
