A wave of nausea came over her, and she had to stop to throw up. Her hands were tingling. She wasn’t taking in enough oxygen. She had been running anaerobically. She had no choice but to take the next couple of miles at a more measured pace. Behind her—something like a mile—she could see a flashlight bobbing rhythmically as its owner sprinted along the trail. This gave her a rough idea of how much time she would have, when she reached the Schloss, to get inside and call the police. Right now it was looking pretty favorable. Shaking a little from the nausea but feeling better as her heart and lungs caught up with oxygen debt, she built speed until she had reached the quickest pace she could maintain.
