Just curious (as usual ad infinitum), when is the subjunctive necessary:

"I could imagine a French ghost saying she was guillotined"
or "I could imagine a French ghost saying she were guillotined"?

"I can imagine a French ghost saying she was guillotined"
or "I can imagine a French ghost saying she were guillotined..."

And, to complicate matters a bit further, should all of the above have at least, "I can imagine a French ghost's saying..." blah, blah, blah. I think that apostrophe is probably a better form...

Best regards,
