Keep your friends close and your enemies closer is only good advice if you can tell the difference between the two. The Afterparty, streaming on Apple TV+, is a comedic murder mystery that unfolds on the night of a high school reunion. Each episode is told from a different character's perspective as detectives try to suss out the truth from the friends/ enemies/ frenemies at the reunion afterparty.

Reunions have become a popular setting for mystery and thriller books and often incorporate a "closed circle mystery"  literary device as a small group of people, each with motive and opportunity, seek to uncover the truth—often revealing long-buried secrets along the way. Below is a selection of thrilling reads which all take place at a reunion. If these books are any indication, there are a lot of reasons to never attend a high school or college reunion besides worrying that you didn't keep up with the Joneses.
