When fleeing from Skalice, you'll pass by Theresa's house and hear her call for help as three Coumans are trying to rape her.
You can either fight them (you do not stand a chance...) or just hit one of them and run away. Theresa will have the time to lock herself in.
Another means is to just draw their attention by whistling, saving you the chance to get hit by one of them or by your pusuers.
