mysteries that seem paranormal but end up having realistic explanations

I love when a book keeps you guessing if there are other forces at work or if the circumstances are just a collection of weird coincidences. I recently read God of the Woods and loved it. It kept me hooked wondering if there was a kidnapping, a murder or if there was something paranormal in the woods that was causing the disappearances. Any suggestions for books with a similar feel would be appreciated !
