Puzzle For The Secret Seven

Whilst on a visit to a fair the Seven meet a gypsy woman, selling ginger-bread, and having no money left to buy any she gives them the crumbling bits she can’t sell. The next time the Seven meet this lady and her two children, her shack on the hill top at Hilly-Down is burning to the ground. Thankfully help is at hand and the woman and her children are allowed to stay in an old caravan on Peter’s parent’s farmland. Odd things begin to happen. The old clothes from the scarecrow disappear, and a violin is stolen from an antique shop. This is a true puzzle for the Secret Seven
