A fair point, but my job means it would take an exception level of incompetence

[He's faultlessly friendly, as always. He'd been asked that question before, and settled into what he thought was an appropriately thoughtful frown of disturbed concern. A very good act, he congratulated himself.]

He's a monster, quite obviously.

[Truth.]

The tricky thing is we've only discovered a few of his victims, and his disposal method seems to change. He's careful, never leaving behind any forensic evidence, so I imagine we won't have any luck, there. As far as I understand it, no one has any idea who he'll strike next.

[Of course Dexter knew very well, but he didn't think it quite politic to say so. He only targeted killers (accidents and rule bending was bound to happen to anyone, were they not?) but the media had yet to pick up that little morsel, because some of his victims were never discovered.]

With his victims, there's always so little blood, too. Doesn't make much use of my expertise.

[Another perfectly cultivated frown of soft self depreciation.]

I wish we had more to go on.
