How do you parse 36a?
Fire girl het up by Geordie? (5)
E?HN?
I can fit an Irish girl's name meaning Little fire.
Briish TV shows are difficult for me, never having seen them.
Even then I found the fourth name in the usual EV spot.
I have read the comments but not sure about the two clued entries.
One more hint will help.
I think the ultimate prize has nothing to do with the TV show.
Thanks.
