Her first book took five years to have published having been rejected by six publishers but to this day she remains the best-selling novelist of all time.
Queen of Crime Agatha Christie went on to write 66 novels as well as 150 short stories and plays and her work has been adapted for films, TV shows and the theatre.
But much of her private life remains a mystery – she lived in Wallingford for 42 years before her death in 1976 and a permanent exhibition at the town’s museum pays tribute to her life and career.
This weekend (September 7-9) the museum in High Street is hosting talks, walks and tea to remember the town’s most-famous resident.
She wrote many of her novels at her home Winterbrook House where she lived with her archaeologist husband Max Mallowan. The house is identified now by its blue plaque.
The exhibition takes visitors behind the scenes of her life here, featuring photos and memories of those who knew her as well as handwritten letters revealing her love of pantomimes.
On Friday night find out more about the Queen of Crime from Agatha Christie specialist John Curran in his talk The Life and Crimes of Agatha Christie which will include plenty of references to her life in Wallingford and Cholsey.
John’s talk takes place at Wallingford Masonic Hall at 8pm, tickets £12.
The following night historian and TV presenter Lucy Worsley will entertain with her talk entitled A Very British Murder.
Lucy will be speaking at Cholsey’s St Mary’s Church where Ms Christie is buried, from 8pm, tickets £15.
If you want to get out and enjoy the area while discovering some of the mystery surrounding the author, join the guided walks on Saturday and Sunday. Leaving from the museum at 10am, tickets (£10) include entry to exhibitions at the museum and Cholsey Day Centre and a return trip on the Cholsey & Wallingford Railway.
Exhibitions can be viewed at the Old School in Cholsey as well as at the museum and if you’ve not had your fill of crime yet, why not try the Midsomer Murders town walks?
Wallingford doubles as Causton in the popular TV series starring John Nettles which has racked up its fair share of bodies over the years.
One-hour walks leave from the town hall at 2.30pm on Saturday and Sunday.
