World-weary priest Daniel Kilgore has fallen. Arriving at his church after his usual visit with a prostitute, he is asked to take the confession of his brother Kurt, who works as an agent for a secret intelligence outfit. Daniel listens, grudgingly, more out of duty than love or divine inspiration.

Soon after, Kurt is killed during a covert operation in Bolivia and Daniel finds himself quite literally haunted by his brother. Kurt begs him to look after his wife, who he believes in is danger from the same people that killed him. However, Daniel is reluctant – hostile, really – to do so. He’s not sure of his own sanity, and worse, he was once in love with Amanda until his brother stole him away. He eventually agrees, if only to keep his brother’s spirit quiet.

That night in Amanda’s apartment, just as Kurt had suspected, two hit men appear to kill her and Daniel is quickly overcome (priests don’t get much combat training). In desperation, Kurt’s spirit attempts to enter his brother’s body. As they merge Kurt and Daniel transform into, well, something powerful enough to defeat the assassins and resilient enough to withstand a hail of bullets.

Physically drained and horrified at his brutal actions, Daniel returns to his church, only to find another hitman, Cobra, waiting. Cobra slaughtered the parish priest and Daniel narrowly escapes. Kurt insists that Daniel seek out the organization Kurt once worked for. Upon his arrival, he is drugged and imprisoned, along with some of the people Kurt had rescued in Bolivia, where they had been undergoing some kind of horrific experimentation by a Doctor Schiller. A female prisoner, traumatized and quite possibly insane, tells Daniel that he is Haunt – a spirit caught in the physical realm, bound by blood and unable to move on.

But none of this helps Daniel who now finds himself at the center of a deep conspiracy within Kurt’s old agency. All sides are searching for what is left of Dr. Shiller’s research, none trust Daniel and further blood and betrayal await Daniel and Kurt. And what – or who – is Haunt?

Kirkman (Walking Dead) writes action and violence adeptly – this not a comic for the faint of heart. There are reminders here of other characters like Spawn and Venom. McFarlane drew the 2009-10 series of Spawn and two Spider-Man series in the early ’90s, and those characters’ influence is strong here. If you enjoyed Kirkman & McFarlane’s previous work, and if you’re in the mood for some grimdark action, you should definitely pick up Haunt.
