The specialty of solving human mysteries without opening the book.

means The branch of medicine focused on preventing, diagnosing, and treating diseases in adults, especially complex or chronic conditions affecting the internal organs, often through reasoning, testing, and observation rather than surgery.

from From Latin internus, 'inward, within,' and medicina, 'the art of healing.' The specialty's name is a 19th-century borrowing (via German Innere Medizin) marking it off from surgery — the doctor who studies what's happening inside the body without cutting it open, piecing together the hidden story from clues on the surface.
