This was my first experience with the Warhammer Black Library, and it really delivered!
After playing Space Marine II, I decided to give the 40K books a go, and started by picking up the Eisenhorn Omnibus, which opens with this short story.
As a comic book collector, I was already familiar with Abnett's prowess as a writer, but he excels here at providing so much intriguing and alluring context for the 40K world (Inquisitors, Ordo Malleus, Chaos, The Warp, etc), while also telling an engaging and atmospheric murder mystery!
I am so very impressed!
