Poirot is visited by a distraught girl, Norma Restarick, who fears she may have killed someone but runs away, telling him that he's too old rather than explaining further. By coincidence, Poirot's friend Ariadne Oliver lives in the same apartment block as Norma and her two roommates and recently went to their party, where Norma was distressed when she was offered ice cream. Norma's ex-nanny, Miss Lavinia Seagram, an alcoholic, also lived in the block but was recently found dead, with the verdict being suicide. Ariadne is unconvinced and searches the nanny's apartment, finding a clue which she puts in her handbag. Soon afterward she is attacked and the bag and its contents are stolen. Poirot visits the Restarick family home in the country, owned by Norma's great-uncle, Sir Roderick, an elderly and half-blind man who is dependent upon Sonia, his young personal assistant (who may well be a gold-digger).

Ariadne Oliver: You do think of things, don't you?
Hercule Poirot: Ah.
Ariadne Oliver: What a calculating mind!... And tortorous! That's what I call it - tortorous!
Hercule Poirot: Am I so calculating, Madame? Am I a solver of puzzles with a heart that is cold? Or are we looking at the greatest of mysteries that life ever throws up... the mystery that even I, Hercule Poirot, will never be able to solve - the nature of love.

Atmospheric, with a true victim.
25 March 2019 | by Sleepin_DragonSee all my reviews

If I'm honest, I'd say the book is decent, but instantly forgettable, as nothing truly memorable happens. This is a fine adaptation, that in my humble opinion improves on the book.

It is a super stylish episode, with terrific sets and some super stylish clothes. The direction is impressive, as it's super sinister and deep. It's directed in a way that throws you off course.

Suchet and Wanamaker are both excellent, they bounce of one another so well. Jemima Rooper I find so impressive, she really does capture the sense of victim, it really is a fine performance, you empathise with her throughout.

I wouldn't say it's one of the best, it isn't, but it's a fine episode nonetheless. 8/10
