Macharius mostly stayed out of the for the search, although he had the Praetorians assist with the search. Shame about his poor record-keeping, what? You would think someone in his line of work would keep files on his employers, in case someone tried to do something like this.

He thinks for a moment, then grins. Perhaps he did! Perhaps Thule kept secret records, undisturbed in his lab, and his killer didn't find them. And perhaps, in our search, we found them. And perhaps we're going to go to Lord Hax with what we've found, information that would unmask the Stalker and, of course, lead to the ruin of her whole family... He winks at Anika. I imagine the Stalker would be quite upset that we'd found that information. Might make her desperate enough to risk an attack. Or even a parley.
