Fun bit of history from CNN Style.

Mary, Queen of Scots used a “spiral locking” technique to seal the last letter she wrote before her execution, indicating that she wanted the contents to remain secret, according to research published in the Electronic British Library Journal.

Mary was interned for 19 years, after which she was executed at the age of 44, according to the royal family website.
