1.Inquisitor

Ian Watson

Inquisitor Jaq Draco of the Ordo Malleus uncovers hints of a vast conspiracy reaching into the highest echelons of the Imperium, and assembles a strange retinue including a deadly Callidus Assassin and an irreverent squat to pursue the truth. His investigation drags him into heresy, daemonic peril, and secrets that could shatter his faith. As the earliest 40k novel ever published, it is gloriously weird and very much of its era.

In the trilogy's finale, Jaq Draco's long descent reaches its climax as the full shape of the conspiracy and the terrible choices it demands are laid bare. Now branded a renegade and meddling with powers no sane Inquisitor should touch, Draco confronts the cost of his crusade against the dark gods. The conclusion pushes its hero to the brink of damnation in classically baroque fashion.
