A late 17th century account mentions an odd incident in Bury St Edmunds involving the local MP who believed himself under attack by witches. The happening is given as contemporary fact with eye witness testimony, rather than as ancient folklore. The account is quite brief and does not give a reason why the MP thought as he did, nor does it describe what happened next. So, being a typical storyteller, I have padded the gaps. The witches in question are not identified but, two years after this incident, the elderly Rose Cullender went to the gallows on charges of witchcraft so I have shoehorned her into the story.
I'm not the first person to utilise this weird occurrence - the wonderful Montague James spun the creepy tale into The Ash Tree.
