Having solved only five clues by Wednesday I gave up on this one but then I saw this thread and thought I'd have another go.
But I think I'm still missing something. Are there extra letters supplied by the word play? I think 30d is DEMETER - met/joined up - er/royalty, but where's the old poet - de?
Nor do I get the wordplay for PERSEPHONE, apart from the phone/call bit.
And, sorry Ginge, but I don't understand what you mean by "foreign got lost" or what it refers to.
I must be having a bad week. Regards.
