While travelling by train, Miss Marple witnesses the strangling of a young woman in another train on a parallel track. The police find nothing to support her story, so she conducts her own investigation, with the aid of her close friend Jim Stringer. They conclude the body must have been thrown from the train near Ackenthorpe Hall. There's only one thing for it - Miss Marple goes undercover as a housekeeper at the Hall. Based on Agatha Christie's 4.50 From Paddington. Also stars James Robertson Justice, Joan Hickson and Rutherford's husband Stringer Davis. https://cosmiccauldronbooks.com.au/p/4-50-from-paddington-agatha-christie/https://cosmiccauldronbooks.com.au/p/margaret-rutherford-dreadnought-good-manners-andrew-merriman/
