As a spy, Severus learned quickly to notice everything surrounding him at first glance. He noted all the open windows, lack of smoke from the chimney, and most foreboding of all, the lack of life emanating from the house.
Quickly dismantling the wards, he entered the house. She had definitely been here. He could see her footprints in the dust on the floor. A search of the dining room and kitchen told him a knife was missing. Nothing else had been touched in this portion of the house. Quietly moving up the stairs, he thought he heard a slight gurgling sound. Severus rushed into the guest bathroom. Nothing was there. Again, he heard the odd sound. It was not pipes, that he was sure of. Frantically, he went from room to room, trying to find the source of this disconcerting noise. Finally in the next to last room was Hermione's old bedroom. He had forgotten she had her own lavatory. He went into the room, wand drawn.
The bath water was pink, almost red. Her body was faintly blue, but he could see she was still breathing, but was definitely struggling for breath. As he was experiencing very painful chest constrictions, he lifted her out of the water. He quickly sealed the open cuts on her wrists and chest. He was no mediwizard, but it would do. Scars did not matter at this point. After conjuring a quilt with a slight warming charm around her body, he apparated them both to Hogsmeade.
Severus found that adrenaline could carry him much further than he anticipated. Once on school grounds, he summoned Dobby. Dobby was instructed to notify Madame Pomfrey of Hermione's impending arrival and status. He was then instructed to notify the headmaster that she had been found.
