Clue: Off to collect daughter, drive perhaps? (3,7)
Answer: GOD WILLING
Explanation: Definition: perhaps?
I think this must be a charade (even though 'to collect' suggests an envelope): GO ('off', particularly as an interjection) plus D ('daughter') plus WILLING ('drive'?). *… but see Cofi @1 for the real wordplay. It is remarkable that I was able to pick up the pieces of the clue without seeing my way to putting them together correctly!
