Anything Agatha Christie is my go to! And Then There Were None is worth the hype just for the ending.
Elly Griffiths - Dr Ruth Galloway series is one of my favorites. She also has other series she writes - I very much enjoyed The Postscript Murders - it was the first in a new series with DS Harbinder Kaur.
You might enjoy Eight Perfect Murders! I loved it.
The Plot and The Other Passenger are also very good
Louise Penny Inspector Gamache series!
Also Wrong Place Wrong Time by Gillian McAllister
Still missing by Chevy Stevens!
Thank you so much for the suggestions!
I just listened to What Lies in the Woods by Kate Alice Marshall and would recommend it!
