Returned to the little house over the sea (5)
I believe the answer is:
Here is my best explanation:
'returned' is the definition.
(homing is a kind of returning)
'the little house over the sea' is the wordplay.
'the little' says to take the initial letters.
'the sea' becomes 'med' (short for Mediterranean).
The initial letters of 'house over' is 'ho'.
'to' is the link.
