Critical

Laurie then took the next case file and hospital record and set to work. Not quite an hour later, the phone rang. As much as she'd been concentrating combined with the near-absolute silence of the deserted fifth floor, the phone's old-style raucous jangle totally startled her. She answered it in a panic before she'd even had a chance to guess who it might be. It was Jack.

"What time did you leave?" he asked.

"I'm not sure. It was three-fifteen when I got up."

"Why didn't you wake me? I missed you when I awoke a few minutes ago."

"I wanted you to get as much sleep as you could."

"Are you exhausted?"

"I've been exhausted for days. Luckily, I didn't have any trouble getting to sleep."

"I'm glad we talked again last night," Jack said, "even if I wasn't when we began."

"I'm glad, too."

"Well, I had better jump into the shower with my antibiotic soap. I'm supposed to be over there at six-fifteen, and it's already twenty after five."

"I forgot to ask: How long does this patella tendon graft take?"

"Dr. Anderson told me a little more than an hour."

"I'm impressed. That's fast."

"He does them so often, he's got it down to a science."

"I'll see you around noon," Laurie said.

"I love you."

"I love you, too," Laurie closed. She heard the click. It sounded so final. Slowly, she replaced the receiver. What was the day going to bring? she asked herself uneasily. She wished she'd hung up first, because she kept hearing the metaphoric disturbing finality of the click over and over in the depths of her brain.

Shaking off any morbid thoughts engendered by the phone, Laurie went back to her matrix, taking yet another case file and its accompanying hospital record from the slowly dwindling stack. To keep from thinking about anything other than the busywork of data entry, Laurie kept at her task compulsively, as if it were a life-or-death necessity. Close to seven, she had only two more to go when Riva arrived.

"What on earth are you doing here so early?"

"I couldn't sleep," Laurie said. "I thought I might as well work."

Riva looked over her shoulder at Laurie's nearly complete matrix. "Very impressive! Have you learned anything earth-shattering?"

"Hardly" Laurie said. She thought for a moment about telling Riva about the unknown and possibly infectious agent she'd found microscopically but then changed her mind. Riva would undoubtedly want to see it, and Laurie was intent on finishing her matrix.

"Are you still pla

"Absolutely," Laurie said. "I want to finish what I'm doing and then go over to see Jack. He's having his surgery today."

"Oh, that's right," Riva said. "I'd forgotten. I don't have Jack to schedule, either. I'd better get down there and see what's come in overnight."

By seven-twenty-five, Laurie had finally made the last entry. She held the matrix up. It was quite extensive, with every known variable she had been able to conjure up to compare the cases.

Quickly she sca

Returning to the matrix and slowing down, she let her eyes pause at each entry in each of the categories, such as age, duration of the procedure, type of anesthesia, et cetera, but still nothing significant caught her attention. Coming to the end of the matrix, Laurie switched her gaze to the wall clock. It was seven-thirty exactly, and Jack's surgery was starting. Laurie could visualize the scalpel cut through the skin, and she winced at the thought. Looking back at her matrix, she felt sorry she had finished filling it in. The process itself had been effective in keeping her mind from thinking about what she preferred not to think about.

Suddenly, Laurie thought of something else she could do to avoid obsessing over what was happening to Jack. She thought of Dr. Collin Wylie in New Zealand and the possibility that he'd gotten the photomicrograph, and the possibility he'd had an opportunity to look at it, and if he had, whether he'd been able to recognize it and respond. There were a lot of ifs, but, undeterred, Laurie went to her e-mail. The main reason she'd not thought about doing so earlier was because the outgoing e-mail had been sent during the night, and she'd forgotten to factor in that New Zealand was on the opposite side of the world, meaning in Auckland it had been morning.

The moment after she'd clicked the appropriate icon and her e-mail opened, she saw it: [email protected] /* */ Eagerly, Laurie opened it.

Dr. Montgomery: Greetings from Down Under I received the photomicrographs from Peter, and I have already duly chastised him for not recognizing an acanthamoeba polyphaga cyst, although I gave him some slack because of the location. I have never seen one in the lung. If you want to see it better, use an iodine stain. As for the evanescent nodularity Peter mentioned, I can only assume that it represents encasement of more of the same MRSA as is seen free in the microscopic field. It has been recently demonstrated in Bath, England, that MRSA can invade and multiply within acanthamoeba, similar to legionella, the cause of Legio
