It kind of ties in to the theory of mine that Hiram has been paranoid over the possbility of Corvo being the Maskes Felon. First of all, he keeps saying He just disappeared after Coldridge... while inside his safety room, so he's paying Daud extra just to try and well...convince himself that Corvo is long gone and dead.
