Father Carlos Martins fights the devil on the daily. Demon possession is his speciality. Freedom is his goal.

As one of the most sought-after exorcists in the Roman Catholic Church, Father Carlos has been called to the most disturbing and vicious cases of possession worldwide. He has witnessed levitation, paranormal violence, foaming at the mouth - everything you've seen from the most terrifying horror movies, but in real life.
His book, The Exorcist Files, tells ten of his most compelling tales of possession, from the fire-fighter whose pact with the devil aged eight gave him supernatural strength in exchange for possession, who sprouted fangs during his encounter with the priest, to the waitress whose encounter with a witch, led her to lure unsuspecting lonely men to become her exhausted sex-slaves.

And uniquely, it reveals the prayers, rituals and secret techniques Martins uses to achieve exorcism, the theology behind them, and how ultimately, it's the victory of Jesus Christ that sets people free.

The Exorcist Files is about how the devil gets in and how to get him out again. Based on the wildly successful podcast of the same name, which has been downloaded over 4 million times since its launch in 2023, The Exorcist Files details Martins' first-hand experiences with real-life exorcisms and discusses them in the context of the history and theology of demonic activity.
The book begins with a foreword written by Cardinal Raymond Burke, the most respected and recognised cardinal in the Roman Catholic Church.
