“It’ll be a formality,” Sachs said. “This’s happened before.”

“Yeah, well, I’m not sure how good it’s going to go.” He sighed. “I screwed up. The whole thing was my fault. I ran a red light.”

Sachs said, “All right, Ron. Get yourself a lawyer. The union’ll set you up.”

He nodded, his eyes flat. “Yeah.”

Rhyme said, “Get on home. Get some rest.”

Sachs asked, “You have wheels?”

“Got a pool car. The director took pity. Have to return it tomorrow. I don’t know, I’ll … I’ll rent one, I guess.” He seemed dazed. “Just wanted to let you know …”

“Call us tomorrow.”

“Yeah, sure. ’Night.”

And, shoulders slumped, he walked slowly out of the town house.

Sachs said, “That’s going to be a tough one. Drugs and running a light and an injury? He’ll beat the narc, but the optics’re bad. Cops I know’ve been fired for less. And, Jesus, there’re reporters already looking over the blotter. They love stuff like this almost as much as an officer-involved shooting.”

“We’ll make some calls,” Rhyme said, though he was thinking that his political pull in the NYPD extended only so far, as his official connection with the department was about the same as that of a Rite Aid clerk or Uber driver.

Sachs said, “I’ll go upstairs.”

They kissed good night, and carting the oxygen tank, she trod up the stairs, not conceding her condition to the extent she’d take the elevator.

Rhyme nodded, and after she left, his eyes settled on the murder board. Where the top had once saidUnsub 89, it now read merelyHale.

Lincoln Rhyme was thinking:

Bishops and rooks and pawns …

I can see the movement of the pieces in our chess game, Charles.

As always, they’re moving with your, yes, clockwork precision, economical and unhesitant.

Moving on squares black and squares white.

Bishops and rooks and pawns …

One space at a time, two, ten …

But, Charles, what eludes me is your strategy. How can I counter this move or that without having a clue as to how you’re going to conquer my king?

Unless and until Rhyme could figure that out, his failure—and he felt it keenly—would have mortal consequences to the citizens of New York.

And, of course, to Rhyme himself. He was very aware of a noteHale had sent to him, a prelude to his trip here, a note that left no doubt what his intentions were:

The next time we meet—and we will meet again, I promise you—will be the last. Farewell, for now, Lincoln. I’ll leave you with this sentiment, which I hope you will ponder on sleepless nights: Quidam hostibus potest neglecta; aliis hostibus mori debent.

Yours, Charles Vespasian Hale
