If you have a possessive proper noun but want to add extra detail by using dashes, how should it be written?
Example:
Penny - our neighbour - has blonde hair.
Would any of these options be correct?
- Penny's - our neighbour - hair is blonde.
- Penny - our neighbour's - hair is blonde.
- Penny's - our neighbour's - hair is blonde.
I know it's not an ideal construction, but I'd still like to know.
