wrote the book

Is the expert

Wrote the book means to be the definitive authority on something, as if you had literally authored the authoritative text: She wrote the book on corporate turnarounds.

The phrase emphasizes unmatched expertise or experience, often with a touch of hyperbole.

Someone who wrote the book on heartbreak has suffered more than most.
