Swamped

You could probably back up into the dressing room. There might even be a window in there - your mind wasn't exactly focused on possible exits when you were looking around.

But then you'd lose the trail. And the human was worried about Nual catching on. You suspect you're close to your main objective. If you lose them now...

...then you're less likely to tip them off about exactly what that objective is, come to think of it. So catching them is less important than figuring out exactly what they were up to. And if your suspicions as to who the human was are correct, well, you know some people you can ask about him.

Still, you should probably make a good show of trying something first, in case they glance back.

Wait. The stool. You tossed it aside and it landed near the door. That might just do the trick. You slip back in and grab it, holding it towards the beast.

It bites off one of the legs. Fortunately, you can see the grebling witnessed your failed attempt. Should make you look sufficiently desperate that they won't have high expectations. You back up and look around for a window.

There is one, but it's closed, and rather small. And it looks like the beast is trying to follow you in - though it gets stuck on the door frame.

But you're not sure how long that frame will hold. You'll have to get the window open...

...except someone's just pulled it open from the outside. And by the looks of things, that someone is Mortimer Flame.

And he's shouting something at you.
