He glanced down automatically at his foot and Sherlock ran at him. “Melissa, drop!”

Brave Melissa threw all her weight forward, pulling the terrorist with her. He struggled with her, off balance, and his finger slipped free of the grenade safety ring. Sherlock took two fast steps, reared back on the heel of her foot and kicked his right wrist, heard the bone crack. He screamed and dropped the grenade. Everyone froze, watched the grenade hit the floor with a loud thump and begin to roll. There was mayhem—yelling and people running to get as far away from the grenade as possible, pushing others out of their way, some of them falling to the floor, a stampede, and over it all security shouting, “Everyone get down! Get down!”

The terrorist was holding on to his wrist, cursing her, but he didn’t come at her, he lunged for the grenade. Sherlock ran after him, kicked him hard in the kidney. He whooshed out a breath as he fell forward onto his hands and knees, hissing in pain as he crawled toward the grenade, now fetched up against a security counter. She prayed none of the security officers would lose it and shoot, since she was so close to him now.

She yelled at him, “Don’t do it!”

He twisted back to look at her, fear and desperation glazing his eyes, screamed curses, and dove for the grenade, his good arm outstretched. She kicked him in the head. He fell forward, sprawling away from the grenade, but still Sherlock saw his fingers reach out and pull the ring free of the grenade. Thankfully, the safety lever stayed attached, still in place, but for how long?

Everyone remained frozen in place, terrified, all eyes on the grenade.

One, two, three agonizingly slow seconds—nothing happened.

She didn’t have handcuffs, so Sherlock planted her foot on the middle of his back and pressed down. “Listen to me, get hold of yourself. If you don’t move, the grenade might not explode and you might survive this.”

The man was heaving for breath, murmuring over and over something she couldn’t understand. A prayer? To Allah? His eyes were tightly closed, one hand still pressed to his head where Sherlock had kicked him. He wasn’t moving now. His other hand lay palm up three inches from the grenade.

He was weeping. He said in a whisper, “You’ve ruined it all. Now they’ll die because of you.” She leaned close, heard him whisper over and over, “Bella, Bella.” A woman’s name, his wife’s name?

“Who’s Bella?”

He didn’t even see her, didn’t see anything beyond himself and what had happened.

She heard the loud buzz of voices all around her, but she ignored them. She looked up to see a man striding toward her, airport security officers flanking him, guns drawn. She’d recognize a Big Dog anywhere. He had to be the chief of security here at JFK, ex-military, tall, built, straight as an oak, with white buzz-cut hair. He yelled to all the huddled passengers, “Do not panic. TSA agents will escort you away from here right now. Slowly, that’s right. Clear the area!”

As Sherlock lifted her foot and stepped away from the man, a half-dozen security agents covered him, picked him up, and dragged him away.

Big Dog shouted, “Okay, Security, back behind that concrete column!” and he led them all briskly away from the grenade, pulling Sherlock with him.

A mustachioed man trotted up. “Pritchett, bomb squad—it’s a grenade? Was the ring pulled?”

Sherlock said, “Yes, about four minutes ago. The safety lever’s still in place.”

“I see it. What a stroke of luck. It could also be defective, but let’s not take any chances. Chief Alport, move your crew back another dozen feet.”

Pritchett said into his portable radio, “Grenade, ring pulled four minutes ago, safety lever still hanging on, could be defective. Let’s not take any chances. No frag bag, bring in the PTCV.”

Sherlock said, “PTCV?”

“Portable Total Containment Vessel.”

Sherlock watched along with everyone else as a few minutes later two members of the bomb squad, looking like green space aliens in their heavy protective suits, walked clumsily to the grenade. One of the men was pushing a large white cylinder on wheels, maybe four feet high, nearly four feet wide, with an opening in the center front.

They studied the grenade, then, after instructions from Pritchett, gently lifted it with long-handled prongs and eased it inside the vessel. They closed the opening, rotated the cylinder. There was a huge collective sigh of relief.

Pritchett said to Big Dog, “You took a big chance getting that close, Chief. I’d say an extra Mass is in order.”

Sherlock and the chief watched Pritchett follow the two suited men wheeling the containment vessel toward an emergency exit. The security people gave them wide berth. Twenty feet short of the doors, there was a loud muffled bang. The containment vessel box shook, but it held.
