I really must get a scan of this, in an ancient book about Lancashire, my dad (who typically reads things like this) found a record of a Mrs Alice Nutter, who was tried and executed as a witch on the information reported by a fellow witch, James Device. Her house was still there and visitable when the book was written, I really must look this up !

Pterry, ever the one for those little details...

Edit : Looked it up, it's apparently a well-known story, and yes, she did invent mad people !
