Here is the tale as told to me by reliable and truthful sources who had themselves heard it from equally fine and upstanding folk who ... well you get the idea. Now many years ago, in the 16th century, to be precise 1590, seems as good a year as any, a young woman by the name of Margaret Read was charged with being a witch and sentenced to be burned in the Tuesday Market Place. She must have been a proper witch as burning was three times dearer than a good hanging by the South Gates. Now Margaret didn't think this burning was such a good idea as she had the strange notion that she wasn't a witch at all. So she prophesied that if she was innocent her heart would leap from her body and strike this building and the first person to leave through the doorway would die instantly. Now the good folk of Lynn weren't too impressed by this and weren't going to waste a good pile of wood, (they'd baked cakes and had ale, for a good witch burning was a merry sight) so they went ahead and gave her the full 180°C for twenty minutes per 500g plus twenty minutes at the end. So anyhow you can see how this is tending. As she slowly roasted her heart leapt out across the market place struck this building and then merrily bounced off towards the river and with a splash was never seen again. Whether young Margaret was heard to say " I told you so" was not recorded but just to be sure that no-one forgot her warning the doorway was blocked up and a witch's heart crudely carved into the wall. So now you have my story you can pass it on to others, every word is true I tell you, as true as my name is William Braquemard.
