When Hermione had first walked into the house, she thought it was empty. The hallway light had been left off, and the house was freezing. Of course, it always was freezing in the winter. It hadn’t been until she walked up the stairs that she noticed the door to the study was slightly ajar, and the light from inside was casting a sliver of light against the floor and the wall across from it. There she found Snape, sitting in an overstuffed armchair in front of the fire with a book open on his lap, his head tilted back slightly, and his eyes closed as he slept.
