Swamped

There's a small spill of something on the floor. You don't know what it is offhand. It's mostly transparent, but it's definitely not water - too thick for that.

And there's another spill not far off. About one pace away, you'd guess. Maybe it's something that got on the intruder's boots.

You follow the splotches and soon enough find the stairs. Oddly, there aren't any more splotches now - maybe the intruder noticed the strange slime and removed their boots. You hope it will be easier to find them once you're upstairs.

You climb up the stairs, and soon hear a noise. They're probably working on opening the window. Maybe these ones are as troublesome as the ones in the hospital.

The fact that you keep hearing similar noises suggests that to be the case. Still, you don't know how close they are to opening it, so you rush towards the noise as soon as possible.

And it's not very difficult to narrow down which room it's in, because the door is still open. You approach carefully, hoping to get a look without being noticed in turn. As it turns out, this isn't very hard because the intruder has his back to you.

There's a human fiddling with the window. He's got one boot slung over his shoulder on a strap; the strange transparent ooze is all over its sole. But what strikes you more is the insignia on the back of his jacket - the Flame family crest.

You think you've found Mortimer Flame. You haven't any idea why he came here, or why he seems to be trying to leave through the window. Frankly, there's a lot going on right now that you're confused about.

But you can sort that all out later. Right now, you need to act.
