To Learn Forgotten Lore

Behind the pleasant smile, I feared another face, 
a darkness in his eyes, and I thought, just in case
it's best to hide the book within some unknown place. 

You will not find it now; it's hidden far too well, 
and I do not know how. I lit'rally can't tell. 
That honorable task unto another fell. 

You stabbed him in the back, and he will speak no more. 
He lies there in his blood, unmoving on the floor. 
Cry to his silent grave to learn forgotten lore.
