I have only just now noticed Freddo's earlier post - I thought he was a haverer - but he was TRYING to tell us something !
Think it's the post before Pastille's but can't see it at the moment.
I think he maybe has the quiz sheet himself (and probably thinks we have too - but I don't) thank goodness ! so he's saying sol(e) is "one" folowed by taws (marbles) for the rest of the clue - if you ken fit I mean ?
