“Cut a window,” Shaul repeated. “Open the stone. VerHauten sets a certain price for the uncut stone. Nonnegotiable. But what they will let you do is open a small facet so you can look inside and see what you’re buying before you buy it. Arik doesn’t even need to do that. He can smell it.”

“Where is Antwerp?” Decker asked.

“Belgium. It’s where VerHauten distributes its stones. Everyone big goes to Antwerp.”

“Why Antwerp?”

“Why do you go to the supermarket to buy milk? Because it’s where diamonds are.”

Decker held back a smile. “I meant why did VerHauten set up distribution there? Why not in South Africa?”

“VerHauten wants a center in Europe. And Belgium gives them easy laws.” Gold paused. “Sometimes for a special client, Arik goes to Belgium and buys big uncut stones. Mostly we go to Israel and buy cut, mid-sized stones. More diamonds are cut in Israel than anywhere else in the world.”

Gold rested the cigarette in his ashtray.

“Still, I don’t know anyone who would hurt Arik to put us out of business. This whole thing is very strange.”

Decker flipped the cover over his notepad. “Yes, it is.”

Gold ran his hand over his face. “Even with the gun, I’m worried. Because I don’t know who this enemy is.” He looked at Decker. “You keep looking for them?”

“For a while,” Decker said. “But without a body, we can’t justify looking for an extended period of time. The family may have taken off on their own accord.”

He stood and so did Gold. “We’ll keep in touch.”

Decker walked over to the door, then paused. “Mr. Gold, do you know where Yalom might keep his passport?”

Gold was quiet for a moment. “No. Why?”

“If he took off for anywhere international, he’d need his passport.”

“I don’t know about Arik’s passport,” Gold said. “Come. I’ll walk you out.”

Decker realized that Gold was inching him down the hallway. Yalom’s partner had been cooperative, even loquacious at times. But Decker couldn’t shake the feeling that Gold was holding back. He spoke at length about VerHauten, but little about Arik and his business dealings.

They reentered the sally port. Yochie was about to buzz them out. She said, “Uh-oh. You get company, Shaul.”

Decker looked at the outside TV monitor. A Chasid with a white beard. He was wearing a tall black hat and long black coat.

“Shnorrers,” Gold said with resignation. “They don’t leave me alone.”

“No, they don’t,” Decker agreed.

Gold looked at him. “You know about shnorrers?”

Decker nodded. Ostensibly, they collected money for worthy causes. Sometimes the worthy causes were themselves. Since he had married Rina, they had invaded his house with outstretched hands, and always at inconvenient times. But Rina had a soft heart. She always gave them something.

Shaul said, “Open the door, Yochie.”
