Agatha Christie - Dead man's folly - BBC full-cast dramatisation

When Ariadne Oliver, the mystery novelist, summons Poirot to join her at a country house in Devon, he is respectful enough of her “intuition” to do so immediately. When she tells him, however, that she is at Nasse House to stage a Murder Hunt at a fête, he is at first concerned that she is wasting his time. But it is not long before he realises that Mrs. Oliver’s fears are fully justified.
