John Constantine, Hellblazer: Pandemonium
When a supernatural force possesses elements of the Iraqi insurgency, British forces bring in John Constantine to handle the problem.
Something terrifying and strange has occurred — outstanding even among horrors faced every day by John Constantine. Intelligence specialists have discovered elements of the Iraqi insurgency may be demonically possessed, and they smell a supernatural rat named “Nergal.” No one in the intelligence agencies is qualified to handle this problem and a private contractor must be employed. Databases identify only one potential candidate: John Constantine.
Constantine is taken from the comfort of his London home to the brutal climates of Iraq due to military coercion, but also because of his interest in a mysterious, beautiful Iraqi agent whose true allegiances are kept in shadow.
