The Moving Finger, by Agatha Christie. A Miss Marple mystery.
Told in the first person by the main character (not Miss Marple, btw) I thought the POV off-putting, initially, and then found myself sucked in. A brother and sister from the city go to the country to convalesce after an injury, settling on Lymstock as a place where nothing at all could happen.
They turn out to be oh-so-wrong, various townspeople die, others fall in love, and an "expert on wickedness", Miss Jane Marple, is finally called in to determine the villain.
