Burrows and Campbell interrogating Corvo.
Interrogation of the Royal Protector is an audiograph found in Dishonored, recorded by Hiram Burrows.
Transcript
Corvo's unconscious again. Though he's taken more punishment than any two men we've brought in for interrogation. When he wakes, we'll start again. Having him sign the confession for her murder isn't critical, but it might be useful to us later. The assassination of an Empress is not a trivial matter.
Location
The audiograph can be found in the Interrogation Room in Coldridge Prison.
