Ex-NYPD officer Chris DeFlorio once patrolled the streets observing the "worst evil that you can imagine." But after coming to faith, he and his wife came to understand the real roots of that diabolical horror. Now, he's on a mission to fight the demonic.

DeFlorio returns to "Playing With Fire" to tell his story and discuss his new book, "Called Into Darkness: Two NYC First Responders Battle the Supernatural."
