The Moving Finger by Agatha Christie

 Miss Marple is called in to solve a murder. She actually has a small role in the story, which is narrated by a man on the scene (not one of the suspects). Marple appears a few pages before the end. It's a decent story but not among Christie's best in my opinion.

Five Little Pigs by Agatha Christie

 Excellent classic Christie with Poirot using the little gray cells to solve a murder in retrospect. I got some of the mystery figured out but not all of it. Recomended.
