In English, the idiom "wears many hats" means to have many roles or responsibilities. For example,
She wears many hats: she's a doctor, a musician, and a writer.
means that this person has many roles in life (a doctor, a musician, and a writer). The 'hat' is synonymous with 'job' in such expressions.
Therefore, "Putting on my detective's hat" means that the person stepped into the role of detective. That's not to say that the person is a real detective - that depends on the context of the passage - but it means the person started asking questions, as a detective would.
This seems to be an example of idiom.
To "put on one's X" in this context means to put yourself in a particular frame of mind. So "put on one's detective hat" means to put oneself in an inquisitive frame of mind, regardless of whether one is a real detective or not.
Similar constructions are "put on one's thinking cap" and "put on one's dancing shoes".
Depending on the context it could either mean - the person put's on a real detective's hat or - the person imagings that he's a detective (might be an idiom).
I've seen examples of the kind where "face" was instead of "hat".
