Sceptic witnessing bank robbery? (7)
I believe the answer is:
atheist
'sceptic' is the definition.
(I've seen this before)
'witnessing bank robbery?' is the wordplay.
'witnessing' becomes 'at' (I can't explain this - if you can you should give a lot more credence to this answer).
'bank robbery?' becomes 'heist' (I've seen this before).
'at'+'heist'='ATHEIST'
Can you help me to learn more?
(Other definitions for atheist that I've seen before include "One denies the existence of a god" , "Unfaithful type" , "Sceptic" , "Person who does not believe in existence of a god" , "One denies the existence of gods" .)
