After dinner David broke the news about Caroline.

"Is she real sick?" Nikki asked.

"She looked very uncomfortable when I saw her," David said.

"I want to go visit her tomorrow," Nikki said.

"I'm sure you do," David said. "But remember, you were a little congested yourself last night. I think we better wait until we know for sure what Caroline has. Okay?"

Nikki nodded, but she wasn't happy.

To be on the safe side, David insisted Nikki do her postural drainage even though she usually only did it in the morning unless she wasn't feeling well. Nikki didn't complain.

After Nikki went to bed, David began to peruse the infectious disease section of one of his medical textbooks. He wasn't looking for anything in particular. He thought there was a chance he might discover something along the lines of the infection he'd envisioned earlier in the day, but nothing jumped out at him.

Before he knew it, David was waking up with his heavy textbook of medicine open on his lap. Shades of medical school, he thought with a chuckle. It had been a while since he'd fallen asleep over one of his books. Checking the clock over the fireplace he was surprised to see it was after eleven. Angela still wasn't home.

Feeling mildly anxious, David called the hospital. The operator put him through to the lab.

"What's going on?" he asked when he heard Angela's voice.

"It's just taking me longer than I thought," Angela said. "The staining takes time. Makes me appreciate the techs who normally do it. I should have called you, but I'm almost finished. I'll be home within the hour."

"I'll be waiting," David said.

It was more than an hour by the time Angela was completely finished. She took a selection of slides and loaded them in a metal briefcase. She thought David might want to take a peek at them. Angela's own microscope was at home so he could easily have a look if he were interested.

She said goodnight to the night-shift techs, then headed out to the parking lot.

She didn't see her old Volvo in the reserved parking area. For a moment, she thought the car had been stolen, then she remembered she'd been forced to park in the far reaches of the upper lot.

Setting off at a brisk pace, Angela quickly slowed. Not only was she carrying a heavy briefcase, but she was exhausted. Halfway across the lot she had to transfer the briefcase to the other hand.

There were a few cars in the parking lot belonging to the night-shift personnel, but they soon fell behind as Angela trudged toward the path that led to the upper lot. Angela noticed that she was entirely alone. There were no other people; the evening shift had long since departed.

As Angela approached the path she began to feel uneasy. She was unaccustomed to being out at such an hour, and had certainly expected to see someone. Then she thought she heard something behind her. When she turned she saw nothing.

Continuing on, Angela started thinking about wild animals. She'd heard that black bears were occasionally spotted in the area. She wondered what she would do if she were suddenly confronted by a bear.

"You're being silly," she told herself. She pushed on. She had to get home; it was after midnight.

The lighting in the lower parking lot was more than adequate. But as Angela entered into the path leading up to the upper lot, she had to pause for a moment to allow her eyes to adjust to the darkness. There were no lights along the path, and dense evergreen trees on both sides formed a natural archway.

The barking of a dog in the distance made Angela jump. Nervously she moved deeper into the tunnel of trees, starting up a run of stairs constructed of railroad ties. She heard crackling noises in the forest and the rustling of the wind high in the pine trees. Feeling frightened, she recalled vividly the episode in the basement when David and Nikki had scared her, and the memory made her even more tense.

At the top of the stairs the path leveled and angled to the left. Up ahead Angela could see the light of the upper parking lot. There was only another fifty feet to go.

Angela had just about calmed herself when a man leaped out of the shadows. He came up on her so suddenly she didn't have a chance to flee. He was brandishing a club over his head; his face was covered by a dark ski mask.

Staggering back, Angela tripped on an exposed root and fell. The man flung himself at her. Angela screamed and rolled to the side. She could hear the thump of the club as it sliced into the soft ground where she had been only seconds before.

Angela scrambled to her feet. The man grabbed her with a gloved hand as he began to raise his club again. Angela swung her briefcase up into the man's crotch with all the strength she could muster. The man's grip on her arm released as he cried out in pain.

With the route back to the hospital blocked by the wheezing man, Angela ran for the upper lot. Empowered by terror Angela ran as she'd never run before, her flying feet crunching on the asphalt. She could hear the man behind her, but she didn't dare to look. She ran up to the Volvo with one thought in mind: the shotgun.

Dropping the briefcase to the pavement, Angela fumbled with her keys. Once she got the trunk open, she yanked the manila paper from the shotgun. Snatching up the bag of shells she hastily dumped them into the trunk. Picking up a single shell, she jammed it into the gun and pumped it into the firing chamber.

Angela whirled about, holding the gun at waist level, but no one was there. The lot was completely deserted. The man hadn't given chase. What she heard had been the echo of her own footfalls.

"Can't you do a little better than that?" Robertson asked. " 'Sorta tall.' Is that it? That's hardly a description. How are we supposed to find this guy if you women can't describe him better than that?"

"It was dark," Angela said. She was having a hard time keeping her emotions even. "And it happened so quickly. Besides, he was wearing a ski mask."

"What the hell were you doing out there in the trees after midnight anyway? Hell, all you nurses were warned."

"I'm not a nurse," Angela said. "I'm a doctor."

"Oh, boy!" Robertson said haughtily. "You think this rapist cared whether you were a nurse or a doctor?"

"The point I'm making is that I wasn't warned. The nurses may have been warned, but no one warned us doctors."

"Well, you should have known better," Robertson said.

"Are you trying to imply that this attack was somehow my fault?"

Robertson ignored her question. "What kind of club was he holding?" he asked.

"I have no idea," Angela said. "I told you it was dark."

Robertson shook his head and looked at his deputy. "You said Bill had just been up there in his cruiser?"

"That's right," the deputy said. "Not ten minutes before the incident he'd made a routine sweep of both parking lots."

"Christ, I don't know what to do," Robertson said. He looked down at Angela and shrugged his shoulders. "If you women would just be a little more cooperative, we wouldn't have this problem."

"May I use the phone?" Angela said.

Angela called David. When he answered she could tell he'd been asleep. She told him she'd be home in ten minutes.

"What time is it?" David asked. Then after a glance at the clock, he answered his own question. "Holy jeez, it's after one. What are you doing?"

"I'll tell you when I get home," Angela said.

After she'd hung up, Angela turned to Robertson. "May I leave now?" she asked testily.

"Of course," Robertson said. "But if you think of anything else, let us know. Would you like my deputy to drive you home?"

"I think I can manage," Angela said.

Ten minutes later, Angela was hugging David at their door. David had been alarmed not just by the late hour, but the sight of his wife coming from the car with a briefcase in one hand and a shotgun in the other. But he didn't ask about the gun. For the moment, he just hugged Angela. She was holding him tightly and wouldn't let go.
