14. The Disappearance of Agatha Christie
In 1926, the world was stunned when famed mystery writer Agatha Christie vanished for 11 days, only to reappear with no memory of her disappearance. Despite endless speculation—from amnesia to a staged escape—Christie never publicly explained her actions.
The true reason behind her vanishing act remains one of literature’s greatest unsolved mysteries, a secret she took to her grave. Christie remains one of the world’s greatest-ever crime writers but the greatest mystery she created was her own.
