When used as a noun, "mystery" can be both countable (e.g., "a mystery") and uncountable depending on whether you are referring to a specific puzzle or the general concept of secrecy. As an adjective, it is often used to describe something that is intentionally kept secret for a surprise, such as a "mystery gift" or "mystery trip." In literature and film, the term refers specifically to the genre. In this context, it is common to see it used interchangeably with "detective story" or "whodunnit."
