By the Grace of God: A Detective Thomas Blade Investigation

In the heart of Chicago, a divine message is a death sentence.

When a woman's body is found propped against a headstone in a quiet cemetery, Detective Thomas Blade is assigned a case that defies all logic. The only clue: the words "By the Grace of God" scrawled in blood above her. The cause of death is strangulation, but the brutality suggests a force beyond human strength.

As more victims appear in cemeteries across the city, Blade and his partner, the sharp-witted P.I. Carla Redding, uncover a terrifying pattern. The killings are not random; they form a sinister, supernatural design. With clues pointing to sulfurous residues, mysterious flashes of light, and a homeless man possessed by a malevolent force, they are plunged into a nightmare that stretches the boundaries of their reality.

Their investigation leads them to a desperate priest and a reclusive professor who speak of portals to another realm and a demonic entity known as the Collector-Satan's own brother, who hunts souls and mocks God with his gruesome displays.

To stop the slaughter, Blade must confront an enemy that bullets can't kill. Facing a battle that will test his courage, his faith, and his very sanity, he must risk everything in a desperate gambit to close a gateway to hell itself.

By the Grace of God is a gripping supernatural thriller that blends procedural crime with chilling paranormal horror, perfect for fans of Dean Koontz and Preston & Child.
