Intervening period in Scrooge's life (8)
I believe the answer is:
meantime
This clue might be a double definition.
'intervening period' is the first definition.
(I've seen this before)
'scrooge's life' is the second definition.
The answer and definition can be both related to time as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'in' is the link.
Can you help me to learn more?
(Other definitions for meantime that I've seen before include "For the moment" , "interval" , "Intervening period" , "interim?" .)
