Forget it is either Edward or Kelly being a rat-catcher? (5,4)
I believe the answer is:
never mind
'forget' is the definition.
(I've seen this before)
'either edward or kelly being a rat-catcher?' is the wordplay.
I cannot really see how this works, but
'being' could be 'vermin' (vermin is a kind of being) and 'vermin' is found within the answer.
'edward' could be 'ned' and 'ned' is found within the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'it is' is the link.
Can you help me to learn more?
(Other definitions for never mind that I've seen before include "Don't worry" , "Forget" , "who cares?" , "It doesn't matter" .)
