[first lines]
Hercule Poirot: Are you feeling better, Hastings?
Captain Hastings: Yes. Yes, I am, as a matter of fact. Takes the pressure off the pancreas, you see.
Hercule Poirot: Hein, the pancreas is nothing. Of the digestive organs, the liver is the key. Look after the liver and life will take care of itself.
Miss Lemon: Your tisane, Monsieur Poirot
Hercule Poirot: Thank you, Miss Lemon. This is what you need, Hastings.
Captain Hastings: No fear; I've tasted it.

very good episode

Hercule Poirot tries to unravel "The Cornish Mystery" in this 1990 episode.

Mrs. Pengelly visits Poirot at his office and confesses that she thinks her husband is trying to kill her. She's very sick to her stomach when he's at home, but when he's out of town, she feels fine. Her doctor insists she has gastritis. There's weed killer missing. Add to this, her husband is a dentist with a new va-va-va voom blond assistant.

Her niece was living with them, but recently moved out. She has no other relatives in town, just a close friend, Jacob Radnor. Poirot and Hastings go to her home in Cornwall the next day, but they're too late. She's already dead.

The husband, Edward, is the obvious suspect, and Hastings' eyes bug out when he sees his assistant! Jacob Radnor, who has just become engaged to Mrs. Pengelly's niece, thinks it would be better if the entire thing were left alone. Poirot says that six months from then, he and Hastings would be back, because there's no way to cover it up, due to "the vox populi." Sure enough, within six months, the husband is arrested. Poirot returns -- because he's sure there's more to the case than Inspector Japp has uncovered.

Really good mystery, with Poirot and Hastings in fine form, as well as Miss Lemon. Poirot is quite funny with Japp, especially at the end.

Very enjoyable and entertaining.
