At last-someones posted an answer to this question quizmaster,-thank you, though I've never heard of a girl called raincloud.Lighthouse family is the only group that springs to mind with those initials and I didn't have success with Level forty-two either..I've put The Wellington Clock at Swanage, but I must stress I am not a Dorset person, and I had to ask for several answers from that section myself.
thanks quizmaster.the answer must be something fairly obscure, or we'd have found it by now. I've even questioned if the letters are correct on the quizzes site, but nobody has bothered to reply.
