I see I'm not alone with this crossword - I can't fathom out how some of the obvious answers relate to the clue.
I'd love to have the compiler explain them!
My problem is 16 across:
Thus, a cop; lone investigator in general (6)
I have ?C???O - I'm sure of the "C" but not so sure of the "O"
My first entry was wrong - my brain has gone to sleep trying to solve this crossword !!!
