“Bill, stop it,” Riley shouted.
Bill was pressing Vaughn against the wall. Riley was afraid he might pull his gun at any second.
“Prove it!” Bill snarled.
Riley managed to get between Bill and Vaughn. She pushed Bill back forcefully.
“That’s enough!” she snapped loudly. “We’re leaving!”
Bill was staring at her, his eyes wild with rage.
Riley turned to Vaughn and said, “I’m sorry. My partner’s sorry. We’ll go now.”
Without waiting for Vaughn to say anything, Riley shoved Bill toward the front door, then out onto the porch.
“What the hell’s the matter with you?” she hissed at him.
“What’s the matter with you? Let me back in there. We’ve got him. I know we’ve got him. We’ll make him show us his driver’s license, find out what his middle name is.”
“No,” Riley said. “We’re not going to make him do anything. Jesus, Bill, you could lose your badge for acting like that. You know better.”
Bill looked like he couldn’t believe his ears. “Why?” he demanded. “We’ve got him. We could get a confession.”
Riley felt like shaking him.
“We don’t know that. Maybe he is our guy, but I don’t think so.”
