The Killings at Kingfisher Hill is the fourth and most recent (2020) title in the estate-authorized continuation of Agatha Christie’s Hercule Poirot series by Sophie Hannah. It’s on sale in the US for $2.99 right now (January 31, 2021). I’ve read and enjoyed a couple of the earlier books in this continuation series.
Hercule Poirot’s Silent Night is the latest (2023) in Sophie Hannah’s continuation of Agatha Christie’s Hercule Poirot books. And for some reason Amazon UK is calling it the “#1 Best Seller in Women’s Fiction Classics”. Perhaps because Agatha Christie and/or Sophie Hannah are female? Although I would assume “Women’s Fiction” would be about women, not necessarily by women. But Hercule Poirot is definitely not female…
And it’s also a bit late for Christmas.
In any case, though, it’s on sale right now at Kindle UK for £0.99, although sadly not on sale (at least as of now) at Kobo UK. I’ve included the Kobo UK link for price-check purposes.
