Agatha and the Truth of Murder is a drama about what writer Tom Dalton and director Terry Loane think Agatha Christie did when she went missing for 11 days in 1926 – truing to solve a real life murder.
The drama opens with an older woman whose name is Florence Nightingale Shore sitting on a train. She speaks with a soldier and soon after an unseen assailant attacks her.
(On January 12, 1920 while riding a train, Shore. the god-daughter of Florence Nightingale was brutally beaten and a few days later died from her injuries. Her murder remains unsolved.)
Fast forward and Ms. Christie is in her home office struggling with her latest manuscript when her maid knocks and says a woman has come to see her. The woman turns out to be Mabel, a nurse who worked with the late Florence.
She wants Ms. Christie’s help to solve her friend’s murder. At first the famous author is reluctant to do so but with her marriage falling apart and remaining stuck with her writing she decides to help.
Actress Ruth Bradley portrays Ms. Christie who with Mabel’s help gather’s the late Ms. Shore’s relatives at the nurse’s home to untangle who inherits. And to do so Ms. Christie pretends to be an estate lawyer.
Things begin smoothly enough but then when one of the guests is shot dead; the drama begins to fizzle. Unlike Hercule Poirot, Ms. Christie does not solve this murder instead Detective Inspector Dicks who arrives at the home to investigate does and he figures out who Ms. Christie is despite her disguise. After this the film tries to recover with the solving of Florence’s murder but sadly it does not get there.
