Through shimmering haze, suss a rich source of wisdom (9)
I believe the answer is:
zechariah
'source of wisdom' is the definition.
The definition suggests a singular noun which matches the answer.
'through shimmering haze suss a rich' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
an anagram of 'rich' is 'chri' which is present in the left over letters.
an anagram of 'haze' is 'zeah' which is located in the left over letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for zechariah that I've seen before include "Biblical book" , "Prophet's book" .)
