But when Sachs mentioned that somebody had broken into her car at the scene—where Baker had been—she remembered the lieutenant’s possibly deceptive behavior. Sachs had called Nancy Simpson, who’d been at the scene, and asked her what time Baker had left.

“Right after you, Detective,” the officer had said.

But Baker had said he’d stayed for almost an hour.

Simpson added that she believed Baker had gone to Brooklyn. Sachs had asked him about being in the borough now to see if Dance could pick up signs of possible deception.

“You broke into my car and went through my purse,” she said. Her voice was harsh. “And you asked a neighbor about me—pretending to be a cop I’d worked with.”

Would he deny it? This could blow up in their faces if Dance and Sachs were wrong.

But Baker looked down at the floor. “Look, this’s all a misunderstanding.”

“You talked to my neighbor?” she asked angrily.

“Yes.”

She eased closer to him. They were about the same height but Sachs, in her anger, seemed to tower over him. “You drive a black Mercedes?”

He frowned. “On a cop’s salary?” This answer seemed genuine.

Rhyme glanced at Cooper, who went to the DMV database. The tech shook his head. “Not his wheels.”

Well, they got one wrong. But Baker’d clearly been nabbed at something.

“So, what’s the story?” Rhyme asked.

Baker looked at Sachs. “Amelia, I really wanted you on the case. You and Lincoln together, you’re an A team. And frankly, you guys get good press. And I wanted to be associated with you. But after I convinced the top floor to bring you on board, I heard there was a problem.”

“What?” she asked firmly.

“In my briefcase, there’s a sheet of paper.” He nodded to Pulaski, who was standing beside the battered attaché case. “It’s folded up. In the top right-hand side.”

The rookie opened the case and found it.

“It’s an email,” Baker continued.

Sachs took it from Pulaski. She read it once, frowning. She was motionless for a moment. Then she stepped closer to Rhyme and set it on the wide arm of his wheelchair. He read the brief, confidential note. It was from a senior inspector at Police Plaza. It said that a few years earlier Sachs had been involved with an NYPD detective, Nicholas Carelli, who’d been convicted of various charges, including hijackings, bribes and assault.

Sachs had not been implicated in the incidents but Carelli had been released not long ago and the brass were concerned that she might have had some contact with him. They didn’t think she’d done anything illegal but if she was seen with him now, it could be, the email said, “embarrassing.”

Sachs cleared her throat and said nothing. Rhyme had known all about Nick and Sachs—how they’d talked about getting married, how close they’d been, how shattered she’d been by his secret life as a criminal.

Baker shook his head. “I’m sorry. I didn’t know how else to handle it. I was told to give them a complete report. Details of where I’d observed you, things I learned about you. On the job and off. Any connection with this Carelli or any of his friends.”
