Where the penthouse is. (Victor's place) (2,3)
I believe the answer is:
on top
'where the penthouse is victor's' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'place' is the wordplay.
I cannot quite understand how this works, but
'place' could be 'top' (top is a kind of place) and 'top' is found within the answer.
The remaining letters 'on' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for on top that I've seen before include "Leading" , "At the summit or in superior position" , "Winning" , "In a dominant position" .)
