In the grim far future, the Inquisition moves amongst mankind like an avenging shadow, striking down daemons, aliens and heretics with uncompromising ruthlessness.

Written by Gaunt's Ghosts creator Dan Abnett, this volume charts the career of Inquisitor Gregor Eisenhorn as he changes from being a zealoyus upholder of the truth to collaborating with the very powers he once swore to destroy!

Part detective story, part interplanetary epic, Xenos, Malleus, Hereticus and the two linking stories are amongst the very best tales ever told by the Black Library.
