I was going to say that Inquisitors tend to be secretive, not exactly the kind of person you'd see featured in any inspirational works -- but on the other hand, there are some notable firebrand witch hunters who love going all out.
I'm still inclined to say it'd be easier to fake a dead Inquisitor still being alive simply by continuing correspondence, and acting like the Inquisitor has just become somewhat reclusive. But this is a matter of interpretation. It certainly does sound like a twisted and paranoid plot to me!
