Persistently asks for money — daft in Scots location (9)
I believe the answer is:
dunsinane
'scots location' is the definition.
(Dunsinane Hill in Scotland)
'persistently asks for money daft' is the wordplay.
'persistently asks for money' becomes 'duns' (to dun is to demand payment for a debt).
'daft' becomes 'inane' (I've seen this before).
'duns'+'inane'='DUNSINANE'
'in' is the link.
(Other definitions for dunsinane that I've seen before include "Hill mentioned with Birnam Wood in Macbeth" , "Till Birnam wood remove to - (Macbeth)" , "Until Great Birnam wood to high - hill shall come against him (Macbeth)" , "Castle near Birnam Wood (Macbeth)" .)
