Landowner in place of seclusion with daughter (5)
I believe the answer is:
laird
'landowner' is the definition.
(Scottish term for a landowner)
'place of seclusion with daughter' is the wordplay.
'place of seclusion' becomes 'lair'.
'with' is a charade indicator (letters next to each other).
'daughter' becomes 'd'.
'lair'+'d'='LAIRD'
'in' acts as a link.
(Other definitions for laird that I've seen before include "Scottish squire" , "Scots landowner" , "One's landed in Scotland" , "He's landed in Scotland" , "Scottish owner of large estate" .)
