One of three Inquisition stories originally released as audio dramas (in Thorn and Talon) before the prose versions were made available, Dan Abnett’s Master Imus’ Transgression is a short story in which we see Eisenhorn in his youth, still an interrogator under inquisitor Hapshant. Master Imus, a quiet and honest man dedicated to his life as a book-keeper, comes to Eisenhorn to confess his unwitting involvement in an unusual crime – or a transgression, as he puts it. What seems at first to be a strange, inconsequential confession turns out to reveal something much more sinister beneath.
