"What are they throwing away? Knapsacks?"
"They seem to be shouting at people at the side of the crowd." Cavanaugh stared at the monitors.
"Men standing against walls," Jamie said. "They all have knapsacks. Here, here, here, and… My God, once you notice them, they seem to be everywhere."
"I hate to imagine what's in them." An agent picked up a microphone. "Surveillance One to all units."
As the agent described what he saw on the screens, Cavanaugh pointed toward the one that showed Carl. "What street is he on?" he asked another agent.
"Girod near Fulton."
Cavanaugh grabbed a lapel microphone and an earbud. "Keep telling me which direction he's taking."
Before Jamie had a chance to think about going with him, Cavanaugh opened the door and jumped to the street.
"Grab the guys with the knapsacks!" the agent said into a microphone. "For God's sake, be careful. We don't know what's in them."
When Jamie jumped to the street, Cavanaugh had disappeared into the crowd.
