What do you believe in? Or what would you like to believe in?

Dear all,
Hope you are having a good week. Before I start I would like to apologise to those who wrote in with the correct answer the week before last and I didn't mention them. the reality was we had a problem with the Internet and I hadn't received them before I wrote last week's piece. So, without further ado, congratulations to Catherine, "S", Hector and Juan Carlos - and yes it was that easy!
I have checked and rechecked the emails replying to last week's puzzle and I haven't found any that gave the answer.
