Determined on parting from black American, touring divorce hub in confidence (5,4)
I believe the answer is:
entre nous
'in confidence' is the definition.
('between us' in French)
'determined on parting from black american touring divorce hub' is the wordplay.
I cannot quite understand how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found in the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
'american' could be 'us' (United States) and 'us' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for entre nous that I've seen before include "in secret" , "private" , "Between ourselves (French)" , "in confidence" .)
