CHAPTER 11
    The object in Langdon’s hand felt surprisingly heavy for its size.
    Slender and smooth, the polished metal cylinder was about six inches long and rounded at both ends, like a miniature torpedo.
    “Before you handle that too roughly,” Sienna offered, “you may want to look at the other side.” She gave him a taut smile. “You say you’re a professor of symbols?”
    Langdon refocused on the tube, turning it in his hands until a bright red symbol rolled into view, emblazoned on its side.
    Instantly, his body tensed.
    As a student of iconography, Langdon knew that precious few images had the power to instill instantaneous fear in the human mind … but the symbol before him definitely made the list. His reaction was visceral and immediate; he placed the tube on the table and slid back his chair.
    Sienna nodded. “Yeah, that was my reaction, too.”
    The marking on the tube was a simple trilateral icon.

    This notorious symbol, Langdon had once read, was developed by Dow Chemical in the 1960s to replace an array of impotent warning graphics previously in use. Like all successful symbols, this one was simple, distinctive, and easy to reproduce. Cleverly conjuring associations with everything from crab pincers to ninja hurling knives, the modern “biohazard” symbol had become a global brand that conveyed
danger
in every language.
    “This little canister is a biotube,” Sienna said. “Used for transporting dangerous substances. We see these occasionally in the medical field. Inside is a foam sleeve into which you can insert a specimen tube for safe transport. In this case …” She pointed to the biohazard symbol. “I’m guessing a deadly chemical agent … or maybe a … virus?” She paused.“The first Ebola samples were brought back from Africa in a tube similar to this one.”
    This was not at all what Langdon wanted to hear. “What the hell is it doing in my jacket! I’m an art history professor; why am I carrying this thing?!”
    Violent images of writhing bodies flashed through his mind … and hovering over them, the plague mask.
    Very sorry … Very sorry
.
    “Wherever this came from,” Sienna said, “this is a very high-end unit. Lead-lined titanium. Virtually impenetrable, even to radiation. I’m guessing government issue.” She pointed to a postage-stamp-size black pad flanking the biohazard symbol. “Thumbprint recognition. Security in case it’s lost or stolen. Tubes like this can be opened only by a specified individual.”
    Although Langdon sensed his mind now working at normal speed, he still felt as if he were struggling to catch up.
I’ve been carrying a biometrically sealed canister
.
    “When I discovered this canister in your jacket, I wanted to show Dr. Marconi privately, but I didn’t have an opportunity before you woke up. I considered trying your thumb on the pad while you were unconscious, but I had no idea what was in the tube, and—”
    “MY thumb?!” Langdon shook his head. “There’s no way this thing is programmed for
me
to open it. I don’t know anything about biochemistry. I’d never have anything like this.”
    “Are you sure?”
    Langdon was damned sure. He reached out and placed his thumb on the finger pad. Nothing happened. “See?! I told—”
    The titanium tube clicked loudly, and Langdon yanked his hand back as if it had been burned.
Holy shit
. He stared at the canister as if it were about to unscrew itself and start emitting a deadly gas. After three seconds, it clicked again, apparently relocking itself.
    Speechless, Langdon turned to Sienna.
    The young doctor exhaled, looking unnerved. “Well, it seems pretty clear that the intended carrier is you.”
    For Langdon, the entire scenario felt incongruous. “That’s impossible. First of all, how would I get this chunk of metal through airport security?”
    “Maybe you flew in on a private jet? Or maybe it was given to you when you arrived in
