An example of Arts and Crafts architecture. Albert (mentioned) - deceased pet of the Tripp sisters.Darren McSweeney as Intellectual on Bus (uncredited).Jestyn Phillips as Steward (Hastings calls him 'Walter').She does not commit suicide but confesses and is arrested. In this adaptation, Bella is present at the denouement.Bob has a much larger role in the plot than in the original.He then calls Bella asking for Jacob, thinking he might have some phosphorus, perhaps suspecting, as everyone else, that Jacob killed Emily. He deduces that this might be phosphorus. In this adaptation, he learns from Miss Lawson later about the 'green haze'.In the book, after Grainger concludes Emily died from natural causes, he takes no further part in the plot. Why he did not detect the garlic smell pointing to phosphorus poisoning is not explained. He hasn't lost his sense of smell here.There is an added plot element of a romantic relationship between Grainger and Miss Lawson.Dr Grainger has a much larger role in this adaptation:.In the original he makes the same offer, but this was to encourage them to talk to him. To keep them out of trouble he pretends that he might find a way to claw back their inheritances and advises them to do nothing in the meantime. However this is thwarted by the painting of General Arundell falling down which wakes up Miss Lawson. After Charles and Teresa learn that they have been disinherited, they organised a break in to Littlegreen House to steal some valuables.In this seance, Isabel (supposedly speaking as Emily) fingers 'Robert Arundell' as her killer. After Emily's death, there is also an added seance by the Tripp sisters which Poirot attends and to which all the suspects are invited.This upsets Bella and forms part of her motive as more money might have enabled them to live on in England. In this adaptation, Jacob wants to leave and go back to Greece (not Smyrna) partly because he cannot practice in England because of prejudice against foreigners. Poirot and Hastings help to evacuate Bella and the children and hide them at the Tripp sister's house. Bella explains that these injuries are from Jacob's beatings. There is a side plot about Bella telling Poirot she is afraid of him, and Dr Grainger telling him he saw injuries on the back of Jacob's son (the children are named Alexis and Katya here). Many people, including Hastings, seem to suspect it is him or else dislike him. He is sometimes hot tempered and even violent.

Jacob Tanios is made up to be slightly more sinister.

Emily goes out into the garden and emits the green haze and then falls dead.

In the original, Emily has a seance with Miss Lawson and the Tripp sisters where she emits a green luminous haze.

Poirot has the vitamins analysed and the mixture is found to be harmless.

Like in the original story, Jacob Tanios does give Emily a bottle of vitamins but here, instead of pouring it away, she actually takes some on the night she died, thus increasing the suspicion on him.

Poirot himself advises Emily to change her will after she has taken the fall down the stairs.Poirot is there from the beginning because Hastings is a friend of Charles and they have come to Windermere to witness his water speed record attempt. The plot device of a belated letter sent to Poirot after Emily's death is omitted.Charles, for example, is a speed boat enthusiast making a world water speed record attempt on Lake Windermere. The backstories of some of the Arundell clan are changed.Added plot elements are largely for dramatic interest and do not alter the main premise. The plot is, however, largely similar to the original novel. Littlegreen House is there and most of the Arundell clan also live nearby. The setting to changed from Market Basing to the Lake Windermere area.
