That doesn't seem like something you'd give to someone who you are planning to murder at all. 

She says thank you, though they won't understand her. 

She can keep doing the spell for a while as long as she keeps catching it when it ends.

They are not infinitely entertained by it, but she has a rotation of the large group of people who live in this farmhouse throughout the day and somebody drags his knitting in so he can watch while he works on a poncho.

It is not ideal to have a bunch more people knowing she has magic but it's better than being murdered in her sleep. When she gets tired she stops, folds her hands, doesn't do much of anything. 

They are puzzled, trade guesses in their language, eventually somebody offers her an afghan and a pillow but it would seem they haven't a spare room.

That's fine! She tries to express being very grateful.

The old lady pats her on the knee. The house isn't quiet, but nobody rifles through her pockets while she sleeps.

She doesn't sleep well, exactly, but eventually she has slept well enough.

She starts preparing spells. Still doesn't have any good combat spells but - she can get a horse, she can get Tongues a couple of times, she can detect thoughts. She doesn't see how to throw more power at the cantrip Jolt but it might be dangerous enough anyway, against random civilians.

She casts Detect Thoughts as soon as she's finished.

Somebody is watching her prepare spells and wondering what language the book is in, it looks very fancy. There's somebody outside training a puppy who isn't thinking about her at all. Somebody in the kitchen kneading bread, wondering if she's an entertainer normally who got split up from her troupe and how she does the lights. Some people beyond that wall are having a foursome but only one of them is thinking about her.

Okay. Safe, for now. 

She casts Tongues and turns to the person who is watching her prepare spells. "Thank you so much for the place to stay. I was sleeping outside when I was attacked by a robber with a knife and then I got lost."

"I thought you couldn't talk Soskat," he says, puzzled and kind of suspicious.

Sigh. She doesn't really want to go through this again but, well, here they are. "I have a spell for it but it only works for a little while. I didn't have it yesterday."

"I told her you were a mage!" he says triumphantly. "I didn't know there were real ones but then you did magic, so I told her - and she said no such thing - and I said how many mages would you have to see, before you'd know they were real, huh, eleven or something, who ignores ten and is like 'ah yes' after eleven - and I was right."

" - yeah, you were, good for you. Magic's hard, in lots of places I think they just haven't learned how to - make people who can do it. Even where I'm from most people can't."

"How do you make somebody who can do it?"

"I haven't done it yet personally but they have to be very clever, good at math and at visualizing things in space and at thinking ahead five steps and holding lots of things in your memory."

"That doesn't sound that complicated..."

These people are so powerful and the church of Asmodeus here will be so valuable. "Well, then I don't know why there aren't more wizards here. As far as I know that's all there is to it."

"Maybe there's a secret your maker didn't explain to you," he says dubiously. "Maybe they were concentrating so hard on making you smart and mathy they weren't sure you'd do everything else they wanted? And they wanted to keep it to themselves?"

"Hmmm, could be. I guess I won't know for sure until I try to do it myself. Or try to teach someone smart and mathy, maybe I should do that first. - maker's dead. Magic accident, about a year ago." She still has Detect Thoughts up so she can see how the cover story goes over.

"...you're not going to have a magic accident and blow up our house, are you?"

"No, no, absolutely not. Trying to invent new spells can be dangerous but I have never done it because I don't like doing dangerous things. Using existing spells is perfectly safe."

"Okay..." He's kind of worried she's lying so they won't kick her out of the house, which they prefer not-blown-up, but he's not going to unilaterally kick her out on this suspicion. "What spells exist?"

"Uh, I know the one for the lights, and one for flavoring food or warming it up or cooling it down, and I can clean clothes and mend things and make a magic horse to ride."

"What kind of flavors?" he wonders. "What's magic about the horse? ...and how come you walked here?"

"Didn't have a magic horse prepared. I have to set up my spells after getting a good night of sleep and I hadn't slept well for a couple of days so I was mostly out."
