Scientists claim to have cracked the secret behind the success of all-time best-selling novelist Agatha Christie. They believe the Devon born writer used a technique which made her books almost impossible to put down.
Scientists believe Torquay born novelist Agatha Christie used words that invoked a chemical response in readers that made her books "literally unputdownable".
A neurolinguistic study of more than 80 of her novels concluded that her phrases trigger a pleasure response which cause people to seek them out again and again.
At shortly after 9.30 p.m. on Friday 3 December 1926, Agatha Christie got up from her armchair and climbed the stairs of her Berkshire home. She kissed her sleeping daughter Rosalind, aged seven, goodnight and made her way back downstairs again. Then she climbed into her Morris Cowley and drove off into the night. She would not be seen again for eleven days.
Her disappearance would spark one of the largest manhunts ever mounted. Agatha Christie was already a famous writer and more than one thousand policemen were assigned to the case, along with hundreds of civilians. For the first time, aeroplanes were also involved in the search.
