Agatha Christie went on a round the world tour in 1922 accompanying her husband at the time Archie Christie who was a financial adviser for the British Empire Exhibition. This is when she discovered her love of travelling. She made the most of this even down to surfing in Honolulu - what a woman she was definitely ahead of her time. What a fantastic opportunity for anyone to have.
Another mind-blowing fact about Agatha - her book Endless Night written in 1967 - in this book she writes as the first person a young working class man - and at this time she was aged 77. Absolutely amazing!
