Wolf had already seen all he needed to. He had identified the pistol, and he could count. As soon as the guard fired his seventh round, Wolf knew he would have to release the single-stack magazine and replace it with a full one. Wolf knelt on the floor by the wooden side and fired four shots through the wood, then peered at the guard over the wooden section and through a clear inch of the glass. The man had been hit at least twice, once in the head.

Wolf rose to his feet as the girl turned to run. His hand shot out, snatched a handful of her long hair, and jerked her back to him. “I’m not going to be shy about shooting you too, darlin’. Now get me that bag of money.” He swung her around and pushed her back into the vault.

He stood by the door and looked around the foyer. He could see that most people were still standing in a compact herd under Bob Carpenter’s eye, some of them unsuccessfully trying to crane their necks to see the guard’s body.

He stepped back to the vault and looked in at the girl, who had dumped the contents of a carton in the bag. He didn’t care at this point whether she had found him many thousands of dollars or dumped a lot of old deposit receipts in there. The time was rapidly getting used up. He knew from bank robbers he’d met in prison that the second you stepped in and announced it was a robbery, it was like starting a timer. You had to be out before the timer reached its end, or you were finished. He took the bag from the girl and stepped out to the foyer.

He shouted, “All right, boys! Time to go!”

He heard running feet, and in a moment the others were in the foyer too, shouldering the laundry bags full of money.

They stood by the door watching the bank employees and customers while Tony Wagner unlocked the bicycle lock, and then they all backed out. Tony reattached the lock to hold together the door handles on the outside and ran to catch up with the others.

As Leah Hawkins drove toward the bank, she held her phone in her hand and stared at the screen. The car was still there. But as she watched, it began to move, going backward. Then it went forward. They were leaving.

She was still a mile behind them, and they were turning again, heading west. They were going toward the river.
