This time he must use his unique gifts to locate the cup from which Judas drank at the Last Supper; before it falls into the wrong hands. Anyone who touches the cup will gain tremendous power - but they will also be corrupted.

Angels, demons, sinners and saints are all determined to find the Unholy Grail, no matter what the cost. And it isn't long before they realise exactly who can lead them to it . . .

Agents of Light and Darkness is the sequel to Something From the Nightside and the second title in Simon R. Green's New York Times bestselling Nightside series.
