'notably twisted layer or cladding on masonry's edge?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'he' is the wordplay.
I cannot really understand how this works, but
'he' could be 'henry' and 'henry' is found within the answer.
A single letter 'o' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
