In 1926 verdween Agatha Christie elf dagen spoorloos van de aardbodem, nadat haar echtgenoot haar vertelde dat hij bij haar weg ging. Na een landelijke zoektocht werd ze in een gezondheids-centrum uiteindelijk teruggevonden. Ze verklaarde zich niets te kunnen herinneren van de afgelopen dagen. Een Amerikaanse journalist was de laatste die contact met haar had.
Nee, helaas is Agatha nog niet beschikbaar op Netflix in Nederland.
