My Eyes and How to See Past Them was book on Divination authored by Sybill Trelawney. It was one of the books that Hermione Granger kept on the shelves in her office at the British Ministry of Magic.
This book spoke aloud the beginning of the riddle necessary to find the hidden time-turner:
The first is the fourth, a disappointing mark.

And the third is both a mountain to climb and a route to take.
A turn in the city, a glide through a lake.
