I very rarely find a 40k short story to be all that interesting, as it’s usually just a frame around a battle between characters you haven’t gotten time to know, or two dudes talking in a room for 30 pages. Instead, this was like an episode of a good detective drama, with a tragic twist that, in a very 40k way, reflects a dark truth about the world we live in. Excellent story, and a nice bridge between Eisenhorn books.
