Roger twisted the key and the lock popped open with a click that sounded unnaturally loud in the confined hallway. He thought he heard a high, urgent squeaking on the other side of the metal door, shrugged it off. It was just water or something in all the pipes. He slipped the lock out of the hole, pocketed the keys, and grasped the cool door handle.

He felt very alone for a moment and felt acutely aware of Daisy’s absence. It gave his chest a quick ache. He promised himself that as soon as he confirmed that the furniture was still secure and sealed, he would take Daisy out to their favorite burger joint, where they let her sit with him out on the back patio. He decided he might just throw caution to the wind and order at least two beers tonight. Heck, maybe three. After the day he’d had, he felt like he certainly deserved it.

He twisted the handle.

The door popped open, showering Roger with debris, the air suddenly full of cotton snow, scraps of fabric, and slivers of wood. It poured over and around him like a soft avalanche. An awful, foul odor followed, and in its own way, was almost more powerful than the shredded wreckage. He instinctively breathed through his open mouth; it was as if a tornado had ripped through a furniture store, grinding and chopping everything and throwing all of it against the door.

He took a step backward, out of the mess, and picked some wiry fluff out of his hair. Much of it was somehow wet, and clung to him. He realized that the moisture was actually rat urine. A dead rat slid out of the stuffing near his feet. He still hadn’t figured out that he had just disrupted a gigantic rat nest until he found a baby rat clinging to his tie.

The thing was smaller than a spark plug and neon red. It looked like some kind of crazy Japanese soft candy. He brushed it away with a gag of disgust, then saw another one clinging to his arm. He could hear it squeal in terror. The cry echoed around him, and he realized that the wreckage was full of baby rats. The shrill squeaks filled the hallway. He swatted them away, stumbling back. He stepped on something that felt like a rotten plum, and when he pulled his foot away, he saw that he had just crushed one of the babies.

An adult rat, a giant covered in coarse black fur, squirmed out of the nest and hissed at him.

His nerve broke completely and with a hoarse shout, he turned and lurched back towards the stairs. His pounding footsteps sent vibrations deep into the foundation of the building, and that, combined with the screaming babies, attracted the rats. They erupted out of the open doorway in a cascade of densely muscled bodies, sharp claws, oversize teeth, and naked, segmented tails.

Roger heard something, and risked a look behind him.

The rats swarmed up the hallway with a speed that sent ice-cold panic shooting through his veins. He cried out and tried to run faster. His only chance was to make it through the doorway and somehow shut the door behind him. There. He could see the door now, and forced himself to not think about the horde that filled the hallway, a cyclone of teeth and claws and rage that roared and snapped at his heels.

He slammed into the door, hands slapping at the handle.

It was locked.

“Oh, Jesus,” he whimpered, digging into his pocket for the keys. He refused to turn to see how close the rats were as his fingers closed over the keys. His hand shook as he jammed the key into the handle. The first key was the wrong one. He fumbled with the next key and they slipped out of his sweating fingers and fell through the metal grille.

He had almost a full second to stare at the keys, lying just inches out of reach on the wet concrete, and then the rats were on him. They hit his left leg first, then his right. He had a very clear sensation of the first few bites, those long teeth snapping together into his flesh, like a prehistoric stapler. Rats scrabbled up his body, biting, clawing, tearing, and agony blossomed in his mind. His knees collapsed, and he fell backwards, head propped awkwardly against the door.

The rats tore into him.

And ate him down to the bone.

CHAPTER 40

5:02 PM

August 13

Dr. Reischtal locked the door to the women’s restroom behind him and put the square package on one of the sinks. Bright florescent lights buzzed overhead, which didn’t hurt, but Dr. Reischtal had chosen this particular restroom because of the full-length mirror next to the paper towel dispenser. He set a bottle of medical lotion and a Mini Maglite on the tray over the sinks. He tested the lock one more time, then began to strip.

He removed his clothes with a methodical resolve, folding them neatly and stacking the items carefully on the sink. First was the lab coat. Then the stiff white button-up shirt, then the white T-shirt. Next came his slacks. His socks. And finally his underwear.

He scrutinized his naked body for a few long seconds. He stepped closer to the mirror. He turned the flashlight on his skin and examined the reflection. He started with his skull, moving quickly through the short bristles of gray hair, checking behind his ears, then down to his neck, his chest. He spent a long time studying his armpits. He poked a finger in his belly button and ignored the bizarre signals from the cluster of nerves inside. That was normal. It was empty, and that was all that mattered.

He slowed down again when he got to his crotch, meticulously combing through his graying pubic hair. Nothing. He continued down his legs, and once he had peered between each toe, he turned and started over using a small mirror to inspect his back. When he got to his buttocks, he bent over and spread his cheeks apart, satisfying himself that no multi-legged horror had latched onto the sensitive skin around his anus.

When he was satisfied that no parasite was lurking on his skin, he opened the square package and unfolded the hazmat suit. After squirting a liberal amount of lotion into his palms, he slathered the lotion across his body, this time working from the ground up. When he was finished, the bottle was nearly empty. His skin shone under the fluorescent lights. He knew that he might be forced to wear the suit for a long duration, and the lotion would help.

He stepped into the hazmat suit and zipped it tight.

Sealed in now and secure, he felt his muscles relax slightly. It wasn’t much, about the same as relaxing your fist just enough to let an excited dog pull its leash through your grip, but it was enough for Dr. Reischtal to take a slow breath and let it out of his nose.

He was safe from the bugs.

When Sam woke, Ed was driving through an industrial wasteland on the West Side. Sam stretched and checked his watch. He rubbed his eyes and scraped his tongue against his teeth. He found his flask, took a long sip, and passed it to Ed. “Miss anything exciting?”

“Oh, sure,” Ed said. He took a long drink and handed it back.

Sam watched the abandoned factories slide past. “So what’s our next move?”

“Shit. I been driving all damn day and still haven’t gotten any closer to figuring any of this out.”

“Well, hell. We’re goddamn detectives. Let’s detect.”

“You’re a fucking genius. Wish I’d thought of that.”

Sam watched the cracked pavement, weeds, and sagging, abandoned buildings slide past the window for a while. “I’ll tell you what’s been troubling me. Where the hell are the two guys from Streets and San?”

“Cook County General.”

“Right. But why hide ’em away? Why not let us talk to them?”

Ed was quiet for a moment. “It’s the rats. They caught whatever the rats have?”

“But why cover it up? Why lie to us?”

“Something else is going on. Something they want to keep quiet. Whatever this rat flu bullshit really is, I’m betting it’s a hell of a lot worse than they’re telling us.”
