15 Underrated Mystery and Thriller Novels That (Warning!) Will Make It Hard to Sleep Tonight

Spenser Collins and Dalton Winthrop have very different backgrounds, but both of them become friends at Harvard in The Ancient Nine. When Spenser is invited to join the secret, exclusive Delphic Club founded in the nineteenth century, Dalton gets worried – his great-uncle is one of the Ancient Nine's oldest members, but he is always very cryptic and secretive about it. The two investigate, trying to glean clues about this mysterious club (and the student who tried to sneak into the club's mansion in 1927 and was never heard from again), but the more they learn, the more they put their own lives in danger. Ian K. Smith's novel is the dark academia tale you've been missing in your life!
