The Hanging Tree

This book is located in the Weeping Hollow. It drops from a skeleton located at the tree with three dead bodies hanging from it. This location first becomes available during the quest A Shattered Crown, after assisting Haedrig the blacksmith kill his recently turned wife. The tree can spawn in random spots on the map, but has been located close-by and northwest of the entrance to the Weeping Hollow from entrance to New Tristram. It can also spawn northeast of the exit, a bit further away.

"The cold ground welcomes the foul bodies of these cruel men. They sought to prolong their lives through forbidden magic at great and cruel cost to others. Their evil fed on itself until it consumed them all and they found themselves at the end of a hangman's rope." -Tristram Magistrate
