In a way, he and Nora worked too closely: if they had anything resembling normal jobs, a traditional workplace, the result might have been different, might have been easier, more casual, but this was “love in the trenches,” and with each of them giving so much to Canary, they had little left for each other, or the rest of the world. A partnership so voracious that nobody asked, “How was your day?” in the downtime—mainly because there was no downtime at all.

Such as here. Getting practically naked in front of each other in the least sexual way possible. Because donning a biosuit is the antithesis of sensuality. It is the converse of allure, it is a withdrawal into prophylaxis, into sterility.

The first layer was a white Nomex jumpsuit, emblazoned on the back with the initials CDC. It zipped from knee to chin, the collar and cuffs sealing it in snug Velcro, black jump boots lacing up to the shins.

The second layer was a disposable white suit made of papery Tyvek. Then booties pulled on over boots, and Silver Shield chemical protective gloves over nylon barriers, taped at the wrists and ankles. Then lifted on self-contained breathing apparatus gear: a SCBA harness, lightweight titanium pressure-demand tank, full-face respirator mask, and personal alert safety system (PASS) device with a firefighter’s distress alarm.

Each hesitated before pulling the mask over his or her face. Nora formed a half smile and cupped Eph’s cheek in her hand. She kissed him. “You okay?”

“Yup.”

“You sure don’t look it. How was Zack?”

“Sulky. Pissed. As he should be.”

“Not your fault.”

“So what? Bottom line is, this weekend with my son is gone, and I’ll never get it back.” He readied his mask. “You know, there came a point in my life where things came down to either my family or my job. I thought I chose family. Apparently, not enough.”

There are moments like these, which usually come at the most inconvenient of times, such as a crisis, when you look at someone and realize that it will hurt you to be without them. Eph saw how unfair he had been to Nora by clinging to Kelly—not even to Kelly, but to the past, to his dead marriage, to what once was, all for Zack’s sake. Nora liked Zack. And Zack liked her, that was obvious.

But now, right now, was not the time to get into this. Eph pulled on his respirator, checking his breathing tank. The outer layer consisted of a yellow—canary yellow—full encapsulation “space” suit, featuring a sealed hood, a 210-degree viewport, and attached gloves. This was the actual level A containment suit, the “contact suit,” twelve layers of fabric which, once sealed, absolutely insulated the wearer from the outside atmosphere.

Nora checked his seal, and he did hers. Biohazard investigators operate on a buddy system much the same as that of scuba divers. Their suits puffed a bit from the circulated air. Sealing out pathogens meant trapping sweat and body heat, and the temperature inside their suits could rise up to thirty degrees higher than room temperature.
