“It appears that someone in the area had been illegally breeding American pit bull terriers for use in dogfights,” said Director Swenson, smoothly as you please. “From what we’ve been able to reconstruct, one of the dogs became infected and attacked the others. The pack attacked their handler when he came to see what all the noise was about. The dogs were able to escape, and those large enough to amplify went on to infect individuals all around the area. It became too large to contain shortly after.”

It was a textbook example of a no-win infection scenario. That was the problem. Textbook examples almost never happen in the real world. I saw Becks opening her mouth, probably to say just that. I clamped my hand down on her thigh under the table, squeezing hard. The pressure was enough to cut her off. She shot me a confused look. I tried to look like I was ignoring her, and cleared my throat.

“Would’ve still been nice if you’d sent, I don’t know, a rescue helicopter or something for folks inside the blast radius, but that’s beside the point,” I said smoothly, keeping my hand clamped on Becks’s thigh. “Anyway, I’m sure you understand why we couldn’t call ahead, having lost your number in the explosion and all.”

The explosion didn’t wipe the CDC’s phone number off the Internet, but that didn’t really matter; my excuse was plausible enough that Director Swenson couldn’t get away with calling me a liar, and artificial enough that we both knew I was lying. His nostrils flared slightly from the strain of keeping his expression neutral. I smiled.

“Yes, absolutely,” said Director Swenson. “Now, to what do we owe the honor of this visit?”

“To get a little background, make sure we’re on the same page and everything, you remember my sister, Georgia Carolyn Mason?” Becks winced at the sound of George’s name, probably thinking of my recent tendency to fly off the handle whenever George came up in conversation. In the back of my head, George snorted with brief amusement but didn’t say anything. This was my party. She was going to let me be the one to send out the invitations.

Director Swenson nodded. “I’ve seen her file. Her death was—any death is tragic, but what she accomplished, even after the point of initial amplification, was—it was amazing. You must be very proud.”

“She died in the field,” I said, as flatly as I could. “Just the way she would have wanted to go.”

“I’m sure that must be a great comfort to you.” He sounded like he meant it, too. My hand clenched tighter on Becks’s thigh. It took every inch of self-control I had to peel my fingers away. She didn’t make a sound, even though the way I was squeezing must have hurt.
