In Kelley Armstrong's novel "The Gathering," the protagonist discovers a hidden file under a mattress that contains detailed background information on each student in their class. The file includes personal details such as parents' names, birthdates, and particularly emphasizes their hobbies. Notably, Mina highlights certain interests like wrestling and boxing for one student, Daniel, suggesting an unusual focus on extracurricular activities.

This meticulous attention to hobbies raises questions about the intentions behind compiling such information. It appears more suited for creating profiles for a dating service rather than for any academic or social purpose. This detail hints at an underlying mystery within the narrative and establishes a sense of intrigue about the characters and their relationships.
