The captain turned on the cabin microphone. "Ladies and gentlemen, we have received a new instruction from federal aviation authorities. For safety reasons, Crestline Flight 2286 will divert to Albuquerque, where the aircraft will be met by a security team. Please remain seated and follow crew directions."
A wave of disbelief traveled through the passengers. Preston Vance rose halfway from his seat before a flight attendant motioned him down. "Grounded? Trent, I have a board meeting in Phoenix at two. You promised you were handling this."
"I am handling it, Mr. Vance," Trent replied, though his voice had lost some of its earlier certainty. "I promise you."
He hurried back to Miles and held up the printed notice as though it were an accusation. "You think you did this?"
"I reported what I observed. The authorities made the decision."
"Coincidence," Trent said. "You think one phone call gets a whole flight grounded?"
Miles looked toward the row where he had noticed the altered pouch. "I hope there's nothing there. I really do."
"Twelve minutes to landing," Brand announced after checking the cabin clock, though no one had asked for a countdown. Trent stared at Miles as if searching his face for some trick he could identify and punish. "What's that supposed to mean?" he demanded. "What are you smiling about?"
"I'm not smiling," Miles answered. "I'm trying to make sure everybody gets home."
In seat 21C, Leland Crane heard the word Albuquerque and went very still. His hands had been resting on the armrests, but one moved slowly toward the space beneath his seat.
From the aisle floor, Miles could see the change in angle of his wrist and the way his body leaned forward against the belt. It was a small movement, almost invisible among passengers adjusting their luggage for landing. To Miles, already concerned about that compartment, it was enough to renew the warning.
"Molly," he said when she came past. "Tell security twenty-one C is reaching below the seat again. Right now."
She did not ask whether he was certain. She had learned that certainty was the wrong question; the right question was whether an observation deserved to be checked by someone capable of checking it safely. She passed the message to the federal air marshal traveling aboard the aircraft, a woman in an ordinary blue cardigan named Nora Ellis. Ellis had maintained her cover during the first disturbance because the warning was vague, but the new information was connected to a specific location and a specific action. Her response was controlled, quiet, and immediate.
From his seat two rows behind Crane, Ellis watched the man's right shoulder. She had already noticed that he paid too much attention to the cabin crew's movements and too little attention to the descent announcement. She could not know what was in the pouch beneath him, and she did not intend to guess. She made discreet contact with the crew and positioned herself where she could intervene if the passenger tried to leave his seat or handle the compartment again.
