Hello all~ So, I've recently started reading more books, and have been really focusing on Agatha Christie in particular. I've been enjoying them quite a bit, but I'm really looking for a few more stories like "And Then There Were None". The problem is, I don't even know how to ask for stories that are similar to a search engine. ^^;; Basically, I like the closed circle, the limited number of characters, the murders (obviously) and the puzzle to try and figure out which of the characters is (or are) the murder. If people know the visual novel "umineko no naku koro ni", that's another example of the type of story I'd really like to find more examples of. Thank you very much for any help!
