“Sure. It’s been around since the mid-1800s. It’s reform.” She began playing with her phone. “Started by German Jews. Prime example of Moorish Revival . . . ah, there’s a Tiffany window there. That’s why you want to see it.”

“Not that I need to see it, but as long as I’m here I figure I should educate myself.” He looked up. “Want to come with me?”

“I’d love to.” She stowed her phone back in her purse. “So are you going to tell me how you suddenly became an expert on Byzantine mosaics?”

Decker smiled. “McAdams gave me a history lesson about fifteen minutes before we met to go to the gallery.”

“Why?”

“It had to do with an art theft that happened thirty years ago. Four mosaic icons from a Russian Orthodox church in Rhode Island made by an artist named Nikolai Petroshkovich. What was stolen was done in the style of the mosaics at Ravenna. The timing couldn’t have been more advantageous.”

“You sounded casual but very impressive. What does an old art theft have to do with your case?”

“Probably nothing. I asked McAdams to look up all major art thefts around our town and I’m not about to punish him for being thorough.”

“For once.”

“Yeah, for once. Mostly he just clocks in the hours. Why he signed up for Greenbury Police is still a mystery. He seems to hate everything about his life there.”

“I’m sure there’s a backstory.”

“My opinion? I think he’s secretly writing a screenplay and that’s why he joined any police force that would take him. The guy is pure Hollywood to me.”

“I’m sure it’ll all come out one day.”

A pause. Decker said, “I’d like to talk to the detectives who worked that Rhode Island case if they’re alive. Find out the steps they took to attempt to trace stolen art. I’m hoping that they still live in the area.”

“Maybe we should extend our visit to another day to give you a little more time.”

“You mean more time with Lily.”

“And more time for the twins, too. There’s nothing wrong with that.” The second burger came. Rina pushed it toward her husband. “You take the whole thing. I’m full.”

“You’re just being nice.”

“Honestly, I’m okay.” She took her husband’s hand. “Peter, we moved back east to be closer to the kids. Also, you retired from the big city so we wouldn’t be so rushed about everything. We could stroll instead of jog. It’s so lovely that we’re going to see the Met and Emanu-El together. Please try not to slip into LAPD work mode just because you finally have a real case. Besides, you have Tyler to handle the slack.”

Decker picked up his miniburger and managed not to eat the entire thing in one bite. “You’re right. There is work I can do here and an extra day wouldn’t hurt. I’ll call Mike. I’m sure it won’t be a problem.”

“Thank you.”

“You’re welcome,” Decker said. “But let me tell you something, woman. If there’s a cat in a tree that doesn’t make it because Tyler’s too lazy, I’m going to put the blame squarely on your shoulders.”

AFTER SEEING RINA off, Decker made several phone calls while sitting on a park bench. Temperatures had climbed to the high thirties with no wind: practically spring climate compared to the icy conditions and gray skies in Greenbury. The fresh air felt bracing on his face and woke him from his usual afternoon torpor.

His aim was to narrow the playing field by crossing off as many members of the Sobel family as he could. First to go were the distant relatives who had professed ignorance about the family mausoleum in Greenbury. Next, he spoke to those who did know of the mausoleum’s existence but had never stepped foot in the town. All their claims were verified by quick calls to Ken Sobel. Then he called up Katy Mendel—the jewelry buyer for Max Stewart. She also seemed to be a straight arrow. His leads were disappearing as he checked off each name on his list.

He’d been sitting for over an hour and the chill was starting to get to him. He walked back to his car, cranked up the heat, and spoke from his office on wheels, ignoring the honks and the pleading eyes of motorists aching for his parking spot.

The most interesting group was close family members: those who had been at the funeral last summer and probably knew about the expensive glass panels inside the vault. On the surface, they seemed like poor candidates for hands-on criminal enterprise. Most of them appeared to have the trappings of wealth: good jobs, stable marriages, and tony addresses. When questioned, they seemed appalled by the thefts and even more outraged that he was looking at them with a detective’s eye.

Between phone calls and interviews with the family, the Met and Emanu-El were perfect places to visit with Rina. The museum was open until six. The temple was open tomorrow between ten and four and visitors were welcome without an appointment. Then it was off to Philadelphia to see Cindy, Koby, and the kids.

It was close to six in the evening when Decker headed back to Brooklyn for the family dinner. He was also starved so he hoped that wherever Rachel and Sammy had chosen, the place believed in large portions. The minihamburgers had long been digested, leaving a raw ache inside his stomach. At this point it was all about quantity rather than quality. As he drove, he started thinking about the theft, wondering if McAdams had dug up anything since the last time they spoke.

Arriving in Brooklyn at the kids’ apartment, he was tired and grumpy, but the baby’s smile cheered him up. Soon the space began to shrink as the crowd grew. It was wonderful to see everyone. There were hugs, kisses, and lots of laughter and that was before dinner. Finally, everybody was assembled and Rachel had finished giving the babysitter last-minute instructions. The brood stepped out into the cold night air, Decker’s children walking ahead, catching up with one another’s lives. They talked about movies, songs, and television series that left Decker in the dark.

“Do you know what they’re talking about?” he asked Rina.

“Kinda. You know, we do have Netflix. You can stream a lot of series. That means you watch them all at once.”

“I know what streaming is, Ms. Flipphone.”

“It serves me perfectly well. All I do is make calls and text. Why should I get a new one, especially in a small town where we don’t need an app to know every single gas station or movie theater within a thirty-mile radius.”

Decker felt his own smartphone vibrate. Without checking the caller, he let the call go to voice mail. He watched his kids joke around with each other. “We did something right. They all seem to get along.” His phone vibrated again. He took it out of his coat pocket and checked the prefix. “It’s the police station. Probably McAdams. I should probably take this.”

“Why are they calling so late in the evening?”

“Yeah, that ain’t good.” He slowed his walk. “Go on with the kids. I’ll meet up with you.”

“Do you know where the restaurant is?”

“Actually, I have no idea.” He dithered so long that the call went to voice mail again. He debated whether or not to call back. “Whatever it is, I suppose it can wait until I get fed.”

“That certainly is a change in your previous attitude.”

“Yeah, the difference between being the person in charge and being a peon. Besides, how can I help? I’m three hours away.” They were almost at the entrance of the restaurant when the phone buzzed a third time.

Rina said, “It must be important.”

“Yeah, I guess. Go in with the family. I’ll be with you in a few minutes.” He pressed the button. “Hey, Harvard, what do you have for me?”

“It’s not McAdams, Pete, it’s Mike Radar.”

Decker had asked the captain for another day in Manhattan so he had expected to hear back. But not at eight in the evening. And not with the tone of voice he was using: all business.

Mike said, “How soon can you get back here?”

“How soon do you need?”
