Warhammer 40,000 - Black Library - Ciaphas Cain: Vaine Gloriole

Publisher: Games Workshop

When the flow of weapons that the Astra Militarum desperately needs begins to dry up from a newly founded forged world, the one, the only man (in)able and (un)willing to investigate is sent there... Ciaphas Cain, Legendary Hero of the Imperium.
With his long-coveted retirement in the balance, the most reluctant of the Imperium's commissioners must navigate insidious assassination attempts against his august person, legions of seditious skitarii, heresy in the upper echelons of the Adeptus Mechanicus itself... and a covert adversary, pulling the strings, whose agenda threatens the future of imperial law in the Gulf of Damocles.
