2026, another British three-part series based on an Agatha Christie novel. In fact, the 1929 novel was a sequel to her book, The Secret of Chimneys.

With three parts, the series has the opportunity to create an atmosphere, 1925, still memories of World War I and sadness with those lost. And, once again, an Agatha Christie style British location. And, an occasion which starts happily, even jokingly, leads to a death and an investigation, and the person solving the mystery the young Lady Eileen Brent, nicknamed Bundle.

There are all the Agatha Christie ingredients from her 1920s imagination. And, a strong cast led by Mia McKenna Bruce and such veterans as Helena Bonham Carter and Martin Freeman.

There is always room for another Agatha Christie mystery.
