Crossword Genius

Report on woman's affair (7)

Ross

I believe the answer is:

shebang

Here is my best explanation:

'affair' is the definition.
('shebang' can informally refer to a matter or situ)

'report on woman's' is the wordplay.
'report' becomes 'bang' (I've seen this before).
'on' means one lot of letters go next to another.
'woman' becomes 'she'.
'bang' after 'she' is 'SHEBANG'.
