Facts for heartless dame on the flip side? (7)
I believe the answer is:
details
'facts' is the definition.
(detail is a kind of fact)
'heartless dame on the flip side?' is the wordplay.
'heartless' suggests removing the centre.
'on' means one lot of letters go next to another.
'the flip side?' becomes 'tails' (I can't justify this - if you can you should give a lot more credence to this answer).
'dame' with its centre taken out is 'de'.
'de'+'tails'='DETAILS'
'for' is the link.
Can you help me to learn more?
(Other definitions for details that I've seen before include "Minutiae" , "Small features" , "Particulars, small parts" .)
