Chris Wraight’s short audio drama The Interrogation of Salvor Lermentov is a direct sequel to his excellent novel Vaults of Terra: The Carrion Throne, and as such is somewhat spoilerific (even in its title). It’s a dialogue-heavy two-hander, as Inquisitor Crowl and the captive traitor Salvor Lermentov – voiced by John Banks and David Seddon respectively – match wits in a surprisingly civilised manner. There are no thumbscrews here, just impassioned arguments as two men, both loyal and dedicated in their own way, debate doctrine, history, and the state of the Imperium.
