Inquisitor Eisenhorn is one on the most senior members of the Imperial Inquisition. With his warband he scourges the galaxy in order to root out heresy. When that heresy is found to infiltrate the hierarchy of the Imperium and the Inquisition itself, he must rely on himself alone to deal with it - even if it means making deals with the enemy. All three books of the Eisenhorn trilogy along with two short stories and Eisenhorn's case book and compendium are included in one big volume.
