Forest Dweller

The killer could be anywhere near, hiding under a freaking table would be suicide and trying to leave would alert them to your presence by hearing the doorknob- that, and cause you to be vulnerable when your back was turned. No, the best thing to do would be to search the house, being as quiet as you could. You know martial arts, so if you find the killer you can defend yourself much better than if you were hiding under the table or trying to leave. Besides, the killer might even be waiting outside, knowing that your first instinct would be to leave.
So you're going to search the house- the real question is, where?
