Evil doctor going forwards and backwards in time (4)
I believe the answer is:
noon
'backwards in time' is the definition.
'noon' can be an answer for 'time' (I've seen this before). I am unsure of the 'backwards in' bit.
'evil doctor going forwards' is the wordplay.
'evil doctor' becomes 'No' (Dr No, James Bond villain).
'going forwards' becomes 'on' (synonyms. I am not sure about the 'going' bit.).
'no'+'on'='NOON'
'and' is the link.
Can you help me to learn more?
(Other definitions for noon that I've seen before include "A moment of time" , "12 pm" , "12 o'clock" , "High time of day?" , "when PM starts" .)
