“The Moving Finger” by Agatha Christie

On to the fourth of fourteen Miss Marple books. Although, oddly, Miss Marple was hardly in it! She didn't even appear until page 175 (out of 234). But she did, of course, play a pivotal role in the resolution of the mystery. 

This is the one narrated by the young (and apparently rich) invalid who moves to the countryside with his sister for rest and recuperation. His doctor had suggested they do so in order to find a calm and quiet place to convalesce, but instead Jerry and Joanna Burton are thrust into turmoil: there are anonymous letters, then an unexpected death, and then a murder. Hardly the tranquility they were expecting!

Did I guess whodunnit? Not at all. Once again, I suspected the poor narrator. (Was I meant to?) I found Jerry weird and creepy. I was just sure he was an unreliable narrator who was hiding something from me (like the fact that he was a murderous madman). But it turns out that no, Jerry is just charming and rich, if maybe also a bit impulsive and cryptic.
