private eye

A privately employed detective, as opposed to one working for the police or another authority. For example, The children loved stories about private eyes, and Janey wanted to become one. This expression comes from the term private investigator, the "i" of investigator being changed to "eye," which plays on the idea of a person looking into things. [1930s]
