Behind one of the frailer bookcases, you can find a hole the key fits into. Once it has been slipped in, a stone door starts to materialise around it. It opens to take entrants an unexpectedly long way down — some two floors' span — in a stone room featuring an inevitable dais that holds two (also stone, not much creativity in the interior decoration) altar beds.

The room stinks of excess bleach. Despite best efforts, there are still multiple blood spatters visible on the walls, some dark (aged), some fresher. If you have a character who can sense these things, they'll be able to tell the blood hails from multiple individuals, and some spiritual energy lingers. No flesh. There are clothes littered in a corner — all servant uniforms — along with bird feathers. No flesh, no corpses.

Scattered around the dais are various cups containing wine, potions and inevitably one that's filled to the brim with opiates, for a makeshift anesthetic. You can find cleansed, exceedingly sharp daggers, too.

Enjoy.
