I do have this of course … hope it suffices:

“I  feel I’ve seen several adaptations of “Dead Man’s Folly,” but in reality, the only other one that exists, I think, is the 1986 film starring Peter Ustinov.

This happens to be one of Christie’s strongest and cleverest stories and lends itself well to the screen.

A wealthy man, George Stubbs, has purchased the beautiful Nasse House and is having something akin to a carnival. He has asked the noted mystery novelist Ariadne Oliver to design a murder hunt. Uncomfortable, Mrs. Oliver persuades Poirot to come to Nasse House, as she’s convinced there are problems afoot.

One problem is Stubbs’ temperamental wife, Hattie, who seems immature. The guests include politicians, a secretary, an architect, and the house’s former owner, who lives in a guest cottage. And there are students who traipse through the grounds as a shortcut to their transportation.

A sullen youngster, Marlene Tucker, has been chosen as the murder victim. She then becomes the murder victim for real, the reason unknown. Then Hattie Stubbs disappears, and the ferryman is found dead.

Questions arise: Did Marlene see something that made her a murder victim? Was Hattie kidnapped? And then there’s the “folly,” a misplaced building of no use.

This is a complicated case for Poirot, but he’s up to the task.

Excellent story with high production values and some good acting, most notably from Suchet. Zoe Wanamaker kind of misses it as Ariadne Oliver, going for a low, gravelly voice that doesn’t quite make it. Sinead Cusack does a grand job as Mrs. Folliat, and Sean Pertwee is excellent as George Stubbs.”

Hmmmmm. Apart from my innate dislike of any Poirot post Hastings/Miss Lemon and any Miss Marple post Joan Hickson, there’s this Zoe person, as mentioned above, all crotchety … plus the overall level of acting … just did not seem natural to me, as if they were playacting for all they were worth … Suchet was still good.
