Supernatural detective Jack Nightingale used to be a police negotiator in a previous life - back in the days before he confronted devils and demons for a living.

So when a young woman embarks on a killing spree in a Houston mansion, Nightingale is the perfect choice to intervene.

But there is nothing that Nightingale can do to stop the slaughter. And there is worse to come. More killings. More bloodshed. More young women with murderous intentions.

The killings aren't random - a demon from Hell is orchestrating the massacres as part of a diabolical scheme. And the only way that Nightingale can stop the carnage is to put his own soul on the line.
