Lizzie Borden took an axe
And gave her mother forty whacks
When she saw what she had done
She gave her father forty-one
Everyone is familiar with this little ditty even though the author is unknown. Over the decades since this horrific double homicide there has been great discussion and controversy over whether Lizzie did the deed or not. And if so, what her motives might have been.
Adding to the discussion is this excellent article in Psychology Today by my friend Dr. Katherine Ramsland.
