“He was an assistant and a research fellow. They decided not to offer him a full professor’s contract. Art says politics was behind it. You know how that is in colleges.”

Henry Rhyme, Art’s father, was a renowned professor of physics at the University of Chicago; academia was an esteemed pursuit in that branch of the Rhyme family. In high school Arthur and Lincoln would debate the virtues of university research and teaching versus a private-sector job. “In academia, you can make a serious contribution to society,” Art had said as the boys shared two somewhat illegal beers, and managed to keep a straight face when Lincoln supplied the requisite follow-up line: “That, and the teaching assistants can be pretty hot.”

Rhyme wasn’t surprised that Art had gone for a university job.

“He could’ve continued to be an assistant but he quit. He was pretty angry. Assumed he’d get another job right away, but that didn’t happen. He was out of work for a while. Ended up at a private company. A medical-equipment manufacturer.” Another automatic glance-this time at the elaborate wheelchair. She blushed as if she’d committed a Don Imus. “It wasn’t his dream job and he hasn’t been real happy. I’m sure he wanted to come see you. But probably he was ashamed he hadn’t done so well. I mean, with you being a celebrity and all.”

Finally, a sip of coffee. “You both had so much in common. You two were like brothers. I remember Boston, all the stories you told. We were up half the night, laughing. Things I never knew about him. And my father-in-law, Henry-when he was alive he’d talk about you all the time.”

“Did he? We wrote quite a bit. In fact, I had a letter from him a few days before he died.”

Rhyme had dozens of indelible memories of his uncle, but one particular image stood out. The tall, balding, ruddy-faced man is rearing back, braying a laugh, embarrassing every one of the dozen or so family members at the Christmas Eve dinner table-embarrassing all, that is, except Henry Rhyme himself, his patient wife and young Lincoln, who is laughing right along. Rhyme liked his uncle very much and would often go to visit Art and the family, who lived about thirty miles away, on the shores of Lake Michigan in Evanston, Illinois.

Now, though, Rhyme was in no mood for nostalgia and was relieved when he heard the door open and the sound of seven firm footsteps, from threshold to carpet, the stride telling Rhyme who it was. A moment later a tall, slim redhead wearing jeans and a black T-shirt under a burgundy blouse entered the lab. The shirt was loose and the stern angle of a black Glock pistol was visible high on her hip.

As Amelia Sachs smiled and kissed Rhyme on the mouth, the criminalist was aware, in his periphery, of Judy’s body language response. The message was clear and Rhyme wondered what had dismayed her: that she’d made the slip of not asking if he was seeing someone, or that she’d assumed a crip couldn’t have a romantic partner-at least not one as disarmingly attractive as Sachs, who’d been a model before going to the police academy.

He introduced them. Sachs listened with concern to the story of Arthur Rhyme’s arrest, and asked how Judy was coping with the situation. Then: “Do you have children?”

Rhyme realized that while he’d been noting Judy’s faux pas, he’d committed one himself, neglecting to ask about their son, whose name he’d forgotten. And, it turned out, the family had grown. In addition to Arthur Junior, who was in high school, there were two others. “A nine-year-old, Henry. And a daughter, Meadow. She’s six.”

“Meadow?” Sachs asked in surprise, for reasons Rhyme couldn’t deduce.

Judy gave an embarrassed laugh. “And we live in Jersey. But it’s got nothing to do with the TV show. She was born before I’d ever seen it.”

TV show?

Judy broke the brief silence. “I’m sure you’re wondering why I called that officer to get your number. But first I have to tell you Art doesn’t know I’m here.”

“No?”

“In fact, to tell you the truth, I wouldn’t have thought of it on my own. I’ve been so upset, not getting any sleep, not thinking straight. But I was talking to Art a few days ago in the detention center and he said, ‘I know what you’re thinking, but don’t call Lincoln. It’s a case of mistaken identity or something. We’ll get it straightened out. Promise me you won’t.’ He didn’t want to burden you… You know how Art is. Just so kind, always thinking of everybody else.”

Rhyme nodded.

“But the more I got to thinking about it, the more sense it made. I wouldn’t ask you to pull strings or do anything that wasn’t right, but I thought maybe you could just make a call or two. Tell me what you thought.”

Rhyme could imagine how that would go over at the Big Building. As a forensic consultant for the NYPD, his job was getting to the truth, wherever that journey led, but the brass definitely preferred him to help convict, not exonerate, defendants.

“I went through some of your clippings-”

“Clippings?”

“Art keeps family scrapbooks. He has clippings about your cases from the newspapers. Dozens. You’ve done some amazing things.”

Rhyme said, “Oh, I’m just a civil servant.”

Finally Judy delivered some unvarnished emotion: a smile, as she looked into his eyes. “Art said he never believed your modesty for a minute.”

“Is that right?”

“But only because you never believed it either.”

Sachs chuckled.

Rhyme snorted a laugh that he thought would pass for sincere. Then he grew serious. “I don’t know how much I can do. But tell me what happened.”

“It was a week ago Thursday, the twelfth. Art always takes off early every Thursday. He goes for a long run in a state park on the way home. He loves to run.”

Rhyme recalled dozens of times when the two boys, born within months of each other, would race along sidewalks or through the green-yellow fields near their Midwestern homes, grasshoppers fleeing, gnats sticking to their sweaty skin when they stopped for breath. Art always seemed to be in better shape but Lincoln had made his school’s varsity track team; his cousin hadn’t been interested in trying out.

Rhyme pushed aside the memories and concentrated on what Judy was saying.

“He left work about three-thirty and went for his run, then came home about seven, seven-thirty. He didn’t seem any different, wasn’t acting odd. He took a shower. We had dinner. But the next day the police came to the house, two from New York and a New Jersey trooper. They asked him questions and looked through the car. They found some blood, I don’t know…” Her voice conveyed traces of the shock she would have felt on that difficult morning. “They searched the house and took away some things. And then they came back and arrested him. For murder.” She had trouble saying the word.

“What was he supposed to have done exactly?” Sachs asked.

“They claimed he killed a woman and stole a rare painting from her.” She scoffed bitterly. “Stole a painting? What on earth for? And murder? Why, Arthur never hurt a single soul in his life. He isn’t capable of it.”

“The blood that was found? Have they run a DNA test?”

“Well, yes, they did. And it seemed to match the victim. But those tests can be wrong, can’t they?”

“Sometimes,” Rhyme said, thinking, Very, very rarely.

“Or the real killer could have planted the blood.”

“This painting,” Sachs asked, “did Arthur have any particular interest in it?”

Judy played with thick black and white plastic bracelets on her left wrist. “The thing is, yes, he used to own one by the same artist. He liked it. But he had to sell it when he lost his job.”

“Where was the painting found?”

“It wasn’t.”

“But how did they know it was taken?”

“Somebody, a witness, said they saw a man carrying it from the woman’s apartment to the car around the time she was killed. Oh, it’s all just a terrible mix-up. Coincidences…That’s what it has to be, just a weird series of coincidences.” Her voice cracked.
