Odd, stray hairs parted left, allegedly (6,3,2)
I believe the answer is:
rumour has it
'parted left allegedly' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'odd stray hairs' is the wordplay.
I cannot quite see how this works, but
'odd' could be 'rum' (rum can mean strange or dubious) and 'rum' is found in the answer.
an anagram of 'hairs' is 'rhasi' which is within the answer.
The remaining letters 'out' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rumour has it that I've seen before include "we hear" , "A little bird says" , "So they say" , "It's the word on the street" .)
