Correspondence has fallen into our hands that we were not intended to see. Foulgrin, a high-ranking demon, instructs his subordinate how to deceive and destroy Jordan Fletcher and his family. It's like placing a bugging device in hell's war room, where we overhear our enemies assessing our weaknesses and strategizing attack. To win the battle, we must know our God, know ourselves, and know our enemy. Lord Foulgrin's Letters is written to help us become better acquainted with each.
