Mystery of Agatha Christie's disappearance is 'solved' as author suggests

Now writer Andrew Wilson has unveiled a new theory as to why she vanished with no explanation: that she had left her home intending to take her own life.

Wilson's new novel A Talent For Murder is fictional, but is based on his theory that the truth about Christie’s disappearance has been “hiding in plain sight
