Hi  I am looking for the title to a adult fiction book.     I believe this  is a British setting novel.  The book time period is the  20^th century.    The book is probably more then 10 years old.     The book is all about an older woman.   The  childrens  rihyme applies to the story.   The rhyme is all about a little girl with an hair curl in the middle of her forehead.   When she was good she was good.   When She was bad she was very  very bad.   I think this woman killed numerous people in the novel.  Can someone help me?
