- Curtain. Start to finish.
- The ending of The Hollow. After Gerda Christow goes to her private room and sees a photo of her husband John and their children one last time, she commits suicide by taking potassium cyanide. So heartbreaking.
- Also, the sad music that plays in Appointment with Death, in the scene when Dame Celia Westholme approaches the helpless Lady Boynton to perform the Coup de Grâce on her, is "Dido's Lament (When I Am Laid in Earth)" from the 1689 opera Dido and Aeneas by English composer Henry Purcell. These lyrics say it all as if in a reminder from Lady Boynton:When I am laid, am laid in earth, may my wrongs create
No trouble, no trouble in thy breast;
Remember me, remember me, but ah! forget my fate.
Remember me, but ah! forget my fate.
- The end of Three Act Tragedy. The actor playing Poirot expresses really well the feeling of betrayal he's feeling towards the murderer, his old friend Sir Charles Cartwright.
- The end of "Problem At Sea". Ellie Henderson is genuinely quite sad over Colonel Clapperton's guilt.Ellie Henderson: He didn't do it for me, you know...
- The death of Mrs. Alice Pengelli in "The Cornish Mystery". She'd come to Poirot for help, only to die the very next morning while he was on the way. He takes the fact that it was such a near miss hard.
- "The Double Clue" deals with jewel theft rather than murder, so is ostensibly less sad. However, Japp's job is on the line throughout the episode, leaving him desperate to figure things out. Tellingly, he comes to Poirot for help instead of the typical setup of him being annoyed at Poirot's interference.
- Meanwhile, with Poirot off with Countess Rosakoff for much of the episode, Hastings and Miss Lemon are concerned that their own involvements with Poirot are coming to an end. Miss Lemon in particular is hit fairly hard.
- This adaptation of Elephants Can Remember features Canon Foreigner Mary Jarrow, Dorothea's daughter who takes murderous revenge on behalf of her mother. She is shown to be a broken and embittered Woobie, Destroyer of Worlds and a very tragic figure when Poirot unmasks her.
- In Death On The Nile, while Poirot is full of disdain for Simon, he is absolutely heartbroken over Jacqueline's involvement in the murders. The look of anguish on his face after he lets Jacqueline take matters into her own hands to spare herself and Simon from the gallows says it all.
