A sermon delivered at Mount St., Mayfair?
But I've got no explanation for this one! Could you help me understand?
'a sermon delivered at mount st mayfair?' is the definition.
I know nothing about this answer so I can't tell whether this works.
'sermon delivered at mount st mayfair?' is the wordplay.
I cannot quite understand how this works, but
'sermon' could be 'address' (I've seen this before) and 'address' is located in the answer.
The remaining letters 'good' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
