Archie didn’t think anyone was still alive, but he didn’t have time to check. He could see Karim and Susan twenty feet up ahead, against the wall across from the bathroom that Gretchen had hid in. Susan’s ear was red with blood. She was looking right at Archie, her face twisted in desperation. Karim adjusted the knife at her throat, his eyes on Archie and Leo as he repeatedly jabbed a button on the wall with his elbow.

The elevator.

Archie stepped over a body, his gun raised at Karim, not looking down, feeling his way with his foot, not stopping for anyone, not caring about anyone but Susan.

“Let her go, Karim,” Leo ordered.

Karim made no sign of hearing him. As Archie got closer, he saw that the textile hanging on the wall had been moved aside like a curtain, revealing the hidden elevator’s steel doors. The doors parted silently and Karim twisted Susan around to push her inside. But as he shoved Susan forward, she let out a scream and scrambled backward. Karim threw her against the wall next to the elevator, as a figure stumbled out between the steel doors, his hands at his throat. The figure took a step and then fell to his knees.

Archie recognized the yachting jacket.

“Jack?” Leo said.

The sirens had reached a fever pitch. They weren’t getting louder anymore. They were here.

Karim looked around wildly, and then pulled Susan from the wall. She howled as he twisted her arm behind her, and Archie could see by the shape of her shoulder that it was dislocated. Karim threw her into the open elevator as both Archie and Leo ran for the steel doors. Jack was on the floor in front of the elevator, sputtering, spurting blood, and Leo dropped to his knees next to him. Archie dived for the elevator, but couldn’t get his hand between the doors in time. In that last second, as the elevator doors closed, Archie caught a glimpse of Susan, at Karim’s feet, doubled over and clutching her shoulder, her face contorted in pain. She didn’t look up.

Archie punched the elevator button and it lit up. “Where does this go?” he demanded from Leo.

Leo had pulled the jacket off his father and was trying to press it against Jack’s bloody, gaping throat. He seemed not to hear Archie.

Someone was pounding at the front door, shouting.

“Leo!” Archie said sharply.

Leo looked up. “The new tunnel system,” he said. “It opens up in a large storage room. There’s a hall off it that leads to some offices and some more storage rooms. The door at the end of that hall leads to the tunnel under the lake and comes up in the basement of a house on the other side of the road.”

The elevator doors slid open.
