I recently finished reading The Secret of Chimneys by Agatha Christie and liked the premise, the characters, the setting, the mystery element, and especially, the intrigue. I liked that it was more than just a murder mystery.
I found it a tad convoluted, though, so I’m looking for similar books that are more tightly plotted.
I’ve read The Seven Dials Mystery (which I loved!) and most Poirot and Marple books. Any author and time period is fine.
