“I’m sure of it, Biff. He either kidnapped Brom Zook, and Brom got away, or he drove Brom into hiding. It’s just got to be one or the other.”

“Dietz knew about this pearl fishery, too?” Biff wanted to know.

“Lots of people know about it, Biff. Stories of a fabulous pearl fishery have been circulating in these parts for years and years. The stories come from the Carib Indians. And every once in a while, a Carib comes to the market with a priceless pearl.”

“But no one has ever located the fishery, is that it?”

“That’s right, Biff. Many have tried, Dietz among them.”

“Where does Derek fit into the picture?” Biff asked.

“I’m coming to that. Derek is motherless. He has spent most of his life divided between living here in Curaçao with his father and living with his grandparents in Holland. When Brom Zook started on his hunt for the pearl fishery, he sent Derek to The Netherlands for his schooling. He knew that he wouldn’t be in Curaçao much of the time, and he didn’t like to leave Derek alone.”

“Why did Derek come back? Particularly since his father is missing?” The picture was still somewhat cloudy to Biff.

“I sent for him,” Uncle Charlie said.

“And you sent for me, too. Why both of us?”
