The second was that the closet in the hallway that led to the front door was open. Talese always kept it closed. There was an automated switch in the frame so that when you opened the door, the bulb inside went on. The closet now, however, was dark. She would have to walk past it to get to the front door.

The third thing was that the two deadbolts on the door were turned to the locked position.

Which meant—since the man who’d broken inside had no keys—he was still here.

The defense attorney, approaching the empty witness stand, beside which Lincoln Rhyme sat in his motorized wheelchair, said: “Mr. Rhyme, I’ll remind you that you’re still under oath.”

Rhyme frowned and looked over the solidly built, black-haired lawyer, whose last name was Coughlin. Rhyme affected a pensive expression. “I wasn’t aware that something might have happened to damage the oath.”

Did the judge offer a faint smile? Rhyme couldn’t see clearly. He was on the main floor of the courtroom, and the judge was considerably above and largely behind him.

The testimonial oath in court had always struck Rhyme as an unnecessary mouthful, even with the “so help you God” snipped off.

Do you solemnly swear to tell the truth, the whole truth and nothing but the truth?

Why did swearing have to be solemn? And once one affirmed the first “truth,” was there any point to the overkill? How about: “Do you swear you won’t lie? If you do, we’ll arrest you.”

More efficient.

He now relented. “I acknowledge that I’m under oath.”

The trial was being conducted in New York Supreme Court—which, despite the name, was in fact a lower-level court in the state. The room was wood paneled and scuffed, the walls hung with pictures of jurists from over the years, going back, it seemed, to the days of Reconstruction. The proceeding itself, however, was pure twenty-first century. On the prosecution and defense tables were computers and tablets—the judge had a slim high-def monitor too. There was not a single law book in the room.

Present were thirty or so spectators, most here to see the infamous defendant, though perhaps a few hoping to see Rhyme.

Coughlin, whose age Rhyme figured to be about fifty, said, “I’ll get to the substance of my cross-examination.” He flipped through notes. Maybe there were no books, but Rhyme noted easily a hundred pounds of foolscap between the defense and the prosecution tables.

“Thank you, sir,” said the judge.

Being a criminalist, a forensic scientist aiding in criminal investigation, is only partly about the laboratory; the other aspect of the job is performing. The prosecutor needs an expert witness to present findings in an articulate way and to patiently and effectively parry the defense counsel’s assault on your conclusions. On redirect, a good prosecutor can sometimes rehabilitate a witness battered by the defense, but it’s best not to get into hard straits in the first place. Lincoln Rhyme was reclusive by nature, and loved his time in a laboratory above all, but he was not entirely introverted. Who doesn’t enjoy a little grandstanding before the jury, and sparring with the defendant’s attorney?
