'london arcade in which heather' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'embraced by actor richard?' is the wordplay.
'embraced by' is an insertion indicator.
'actor' becomes 'burton' (Richard Burton).
'richard?' becomes 'ling' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'burton' going around 'ling' is 'BURLINGTON'.
