Hercule Poirot, Agatha Christie's Belgian sleuth, is brought up to modern times in Dead Man's Folly. Normally Christie stories are better set in the period that they were written, but in this case no harm is done. Her detectives are quite eternal.

Peter Ustinov returns as Poirot with Jonathan Cecil as the ever dependable Captain Hastings and he's been invited to another one of those English estates by American mystery writer Jean Stapleton. She's giving one of those mystery hunt games at the estate and the invited guests are going to be the contestants.

It gets really out of hand when three real murders are discovered in the course of this film. A young girl from the village, an old estate caretaker and the wife of the Lord of the Manor Tim Pigott-Smith. And they are connected though how you will be surprised.

I will give you two clues the former owner of the estate Constance Cummings knows a lot more than she is revealing and the arrival of Jeff Yagher from America upsets a lot of well laid plans.

You'll enjoy figuring this one out if you can.
