Rabbit in the sack? (6,4)
I believe the answer is:
pillow talk
'the sack?' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'rabbit' is the wordplay.
I cannot quite see how this works, but
'rabbit' could be 'talk' (I've seen this before) and 'talk' is found in the answer.
The remaining letters 'pillow' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for pillow talk that I've seen before include "Conversation in bed" , "Conversations in bed" , "romantic comedy film" , "Bedtime conversation" .)
