Volume 1 to 3 of Frank's Journal by Charles D'Amico details Frank's transition to a full-blown serial killer. From ending his nephew's life to adopting a stray dog and befriending some of his victims, Frank shares what transpires after leaving the FBI, before landing in prison and catching up with his old friend, Neil. Volume 1 shows what it is like to transition from an FBI agent to a killer. Here, Frank struggles to accept his dreadful actions as what they are. In the second volume, he finally accepts his role as a killer. The last volume details how he commits himself fully to his craft: branding his work and learning and growing as a killer.
