Good memory of whole amount? (5,6)
I believe the answer is:
total recall
'good memory' is the definition.
'total recall' can be an answer for 'memory' (I have seen 'Infallible memory' mean 'total recall' so perhaps 'memory' could also mean 'total recall'). I am not certain of the 'good' bit.
'whole amount?' is the wordplay.
'whole' becomes 'total' (similar in meaning).
'amount?' becomes 'recall' (I can't explain this - if you can you should give a lot more credence to this answer).
'total'+'recall'='TOTAL RECALL'
'of' is the link.
Can you help me to learn more?
(Other definitions for total recall that I've seen before include "Extreme power of memory" , "1990 or 2012 sci-fi film" , "Excellent memory" , "Infallible memory" .)
