Harry does not need to be prompted to explain how he bought a precious bottle of mud. One day, he went to an exclusive shop in London and asked for 'Myrolite', the shop assistant looked puzzled and Harry repeated the word, slowly stressing each syllable. When the woman shooked her head in bewilderment, Harry went to explain the 'myrolite' was a hard, amber-like substance which could be used to remove freckles. This explain evidently conveyed something to the woman who searched shelf after shelf. She produced all sorts of concoctions, but none of them met with Harry's requirement. When Harry put on his act of being wildly annoyed, the assistant promised to order some for him.
