This is the second book in a row I’ve read where the central idea is great, and the characters are interesting, but there just seems to be a big lull in the middle. Once the big crime occurred, it was really just a book of following these characters around as they walked through a nature reserve in the dark, either acting suspiciously or thinking about their suspicions. In the end, the mystery reveal and the twist were good, it just felt like it took ages to get there.
