[OOC: OK, then. There is precedent here for the magically adept, which Tim is, to "notice" many but not all forms of magic almost casually, without resorting to anything as focused as Sister Rose's Empathy spell or Brother Miguel's Divination magic. Let's assume Tim is automatically doing the former, and stopping for more diagnostic spellcraft if something unexpected pops up. So on to some intrigue, with the usual few obvious words put in Tim's mouth:]
The staff of Chateau Dragonslayer knew Tim by now, at least by sight if not deeply. They were used to him asking questions about Clovius, reasonably enough; how else was a new priest going to lead his flock without making a fool of himself? [OOC: Real-world story about a priest who didn't take these precautions, and did make a fool of himself and enemies of some of his people, some other time if you're interested. /OOC:] So at first, when he visited the mansion this day, they responded to his inquiries pleasantly enough, with generalities that basically revealed nothing he didn't already know. As he stayed longer, though, he noticed a change in this behavior. His interviewees became more uncomfortable, their answers more halting, their departures on "urgent business" more hurried.
He also noticed something else. There had always been little bits of magic around the house -- light globes (those had even been adopted in upper-class houses in Veracia, much to the consternation of some religious conservatives who weren't well enough off to have them), something beneath the kitchen sink that disposed of uneaten scraps of food while emitting a "GRRRRR" that had startled Tim the first time he heard it, filmy magic in the trophy room on the Gornch-lizard head, which Tovah had told him would stink to high heaven without it, and so on. This time, however, there was also very distinct magic around two doors. One, Tim knew, led to a small sitting room off the trophy room; he'd been in there previously and seen (and detected) nothing out of the ordinary. The other, more distant and inaccessible but at the same time stronger and more obvious, he sensed briefly at the end of the hall to the servants' quarters, but he could not approach it to learn more. The sitting-room magic yielded to his diagnostic magic easily enough: it was an obvious, and apparently very strong, Ward spell and magical lock -- on a door, note, that he'd passed through several times without incident.
He was standing outside the servants' quarters, pondering whether he dare ask one of the servants what the magic was and whether (all in Luminosita's Service, of course) they'd let him do some diagnostics on it, when he was startled by a sharp "Ahem" from behind him. The speaker had approached silently enough that he had no idea the man (presumably) was there until he spoke. "Father Timothy, beware."
Turning to face this unexpected interruption, Tim saw a man he hadn't seen at Chateau Dragonslayer before. He was tall, at least six feet four, and powerfully built. He wore the uniform of the chamberlain, a button-down tunic, trousers and wide hat, but it scarcely fit him; the chamberlain, Tim knew, was a rather short man. And there was something else about him that Tim couldn't put his finger on, a magical aura that shouldn't have been there. He blinked and remembered his manners. "Luminosita's Peace be with you, good brother," he said. "I was just wondering about possible unholy magic that has --"
He got no further before magic flared in the man's eyes. The tall stranger spoke a single word: "Don't." And Tim found himself unable to finish his sentence.
Worse was to come, or at least it appeared worse at the moment. Tim's military training took over, and he was just starting to assume a ready position when the stranger extended a long arm, so fast that it seemed almost invisible, and touched Tim's forehead. There was a BZZZT of magic ... and Tim knew no more, until he woke up comfortably arranged on a couch in the trophy room, without the slightest idea of how he got there. And looking at him in shocked surprise was Joash, the short, immaculately dressed chamberlain of Chateau Dragonslayer.
