Written by an anonymous prisoner, this missive is something of an autobiography. It tells the tale of how this Khajiit discovered, and then rose to prominence within, the illegal fur and hide trade in Tamriel.
This book is added into the game by the Dawnguard DLC.
It can be found in Dead Drop Falls, on a table in the last room before the Dead Drop Mine zone.
