He raised his eyes to her, made a face. "Well, the gun," he whispered.

"That's nothing!" Linda's eyes flared and her voice snapped. "That's not even been definitely connected to Andrew."

Hal, muzzled, shut up and shrugged at Wu, who then spoke gently to Linda. "I don't believe I've heard anything yet about a gun."

She was prepared to answer. "This was early on, in the first week or so. The police asked Hal if we owned any guns, and Hal told them he had an old registered weapon…"

"Nine-millimeter Glock semi-auto," Hal said.

Again, Linda snapped. "Whatever. And when Hal went to find it, he couldn't." She turned to her husband. "But you know you're always misplacing things. It didn't mean Andrew took it."

Wu touched Linda's arm. "But the police think he did?"

Linda looked at Hal, who answered for her. "They found a casing in his car."

"So what?" Wu asked "Without the gun, you can't have a ballistics test."

"It was just a random piece of junk under the seat," Linda said. "It might have been there forever. It was nothing."

Wu tried to look sympathetic. "So the police didn't specifically refer to that when they came today?"

"No. They just said he was under arrest. They had enough evidence, they said. Something about a lineup," she added.

"He stood in a lineup? You let him do that? Who was trying to identify him?"

Hal North bristled. "I don't know. Some witness. Someone identifying Andrew, obviously."

"And wrongly," Linda said.

"Although," Wu phrased it gently, "as you say, he was there at Mooney's place. So someone might have seen him. Yes?"

"Yes, but…" Linda slapped at the table.

Hal reached out and put a hand over hers. "Look," he said to Wu, "we're not sure why any of this is happening. We don't think Andrew did this."

Linda slapped the table again. "We know he didn't do this."
