This set of novels by Agatha Christie includes: And Then There Were None, Crooked House, and Endless Night. It's was quite enjoyable for me to reread ATTWN and CH. Tho, I have some issues with ATTWN because of the original title/content of the novel. The updated title and story are very interesting, but I still find it hard to get past Chrisite choosing "Ten Little Niggers" as the poem to base one of her mysteries on. Even at the time of writing, I feel this had to be offensive.

Crooked House was a nice reread, tho I'm a bit bothered by the Mamie character, which is so obviously a caricature. Something I didn't notice when first reading the novel years ago. And something I probably would have failed to notice again if I hadn't been rereading it back to back with ATTWN.

Endless Night was amazingly good. About partway thru, I had an idea of what might happen, but it didn't happen how I expected. I wasn't expecting a marginally untrustworthy narrator.
