Right in the middle of lifeless moderates? (4,6)
I believe the answer is:
dead centre
'right in the middle' is the definition.
(I've seen this before)
'lifeless moderates?' is the wordplay.
'lifeless' becomes 'dead' (similar in meaning).
'moderates?' becomes 'centre' (I can't justify this - if you can you should give a lot more credence to this answer).
'dead'+'centre'='DEAD-CENTRE'
'of' is the link.
Can you help me to learn more?
(Other definitions for dead centre that I've seen before include "heart" , "Smack in the middle" , "Position when engine crank and connecting-rod are in line" , "cemetery?" , "bullseye" .)
