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.
