“So what was VerHauten after?”

Decker shrugged. “Let’s keep reading.”

Marge said, “Whatever it was, according to this letter, VerHauten eventually did hand the problem over to its lawyers. I wonder if eventually Yalom engaged an attorney of his own.”

Decker took out another piece of paper from the stack and unfolded it—a preprinted certificate. It looked to be a deed of trust for land in Angola. He showed it to Marge.

She said, “VerHauten wrote about ‘unauthorized land parcels.’ This could be the disputed certificate of ownership.”

“It could be one of many.”

“So Yalom was still investing in Africa. Do you have any idea where Angola is in relationship to South Africa?”

“Northwest,” Decker said. “The two countries are separated by Botswana and Namibia. I looked at a map of Africa after you found Yalom’s passport.”

“Does Angola have diamond mines?”

“I don’t know,” Decker said. “But the countries are contiguous. They probably have similar terrain.”

Marge said, “Maybe Yalom was cutting some sort of side deal with VerHauten, leaving Gold out on ice. That’s why Gold freaked when he found out about Yalom’s passport.”

“But the letters were hostile. If there ever was a deal, something soured pretty quickly.”

They both were silent.

Marge said, “I brought some yellow stick ’ems. Why don’t we tag the papers we’ve gone through.”

Decker said, “Good idea. I’ll take a pile. You take a pile. We’ll write notes, then compare when we’re done.” He fished out a handful of papers.

Marge pulled out her notebook. “I know this sounds farfetched, but do you think that the boys might be in Africa?”

“I suppose it’s a remote possibility.” He sorted through some papers. “After we found the bodies, Davidson assigned a crew to check out the airlines, the cabs, and the buses…free up our time to investigate the murders. I hope they find something soon. I know we haven’t ruled out the boys as suspects. But finding stuff like this…reading Yalom’s hostility and threats….”

“Guy probably made lots of enemies,” Marge said.

“I’m sure.” Decker paused. “If only Arik Yalom had been killed, I wouldn’t be as worried about the kids. But someone also popped Dalia. If someone blew away one innocent bystander, are the boys far behind?”

“If they’re even still alive.”

“A sobering thought.” Decker picked up another batch of correspondence. “One thing at a time.”

He returned his attention to the paperwork. Lots of letters, lots of angry correspondence between Yalom and VerHauten, between Yalom and VerHauten’s lawyers. Decker never did discover an attorney for Yalom.

There were also lots of stock certificates: Consolidated Gems, Southwest Mines, West African Consolidated. Yalom’s stocks added up to thousands of shares in each company. Decker read on. He eventually found a letter to Yalom from Southwest Mines.

The company was announcing bankruptcy.
