SZEGED, HUNGARY

SAM AND REMI WERE IN THEIR HOTEL SUITE, AND SELMA Wondrash was on Remi’s computer screen. “Wendy and Pete and I have done the comparisons and angle measurements and calculations many times and we’re sure that we’ve found the spot that was indicated on the vest. The Roman soldiers of that era could cover twenty-five miles in a day on foot. The Huns were horsemen. When they wanted to, they could probably do twice that distance. But this time they had to transport a heavy load, so we’ve brought the estimate back to about twenty-five. That means we have a distance north along the river of sixty miles and a distance west of twelve miles. Using aerial photography and satellite images, we do find a dry channel with a crescent-shaped accumulation of alluvium on its west, or outer, side. And the later shortening and straightening of the Tisza left the spot not only dry but nowhere near the modern course of the river.”

“You’re using the same reasoning we are,” said Sam. “The cargo must have weighed several tons, so it was loaded on a huge wagon, probably drawn by a herd of oxen. They would have gone across the plains east of the river, where they didn’t need a road, and probably stayed out of sight of the river until the end. In fact, they probably had groups of outriders on all sides to be sure nobody came close.”

“Agreed,” said Selma. “So when we compare the map on the vest with the aerial photographs, we get a spot at 46° 25' 55" north and 19° 29' 19" east. That’s about a hundred thirty miles south of Budapest.”

“What’s there?”

“Well, it could be worse,” she said. “It’s not a cathedral or a nuclear power plant. It’s the Grape Research Institute, in Kiskunhalas. The halas part means ‘fish.’ In medieval times the town was surrounded by lakes, presumably fed by the river. They’re long gone, but the memory lingers on, as does the sandy soil, which is terrific for growing wine grapes.”

“How does a modern person get there?”

“From Szeged, you take Route 55 until you reach Route 53, then switch.”

“We’ll let you know when we’ve figured out how to do this,” Sam said. “We’ve got a whole lot of activity going on at the Tisza River to make Bako’s men think we’ve already found the tomb underwater.”

“If I were you, I’d keep that up,” she said. “Arpad Bako has been investigated for three murders besides Tibor Lazar’s son. And I wish you good hunting. If anything comes to mind that I can do, give me a call.”

“We will.”

The next morning, Sam and Remi went down to the Tisza River as usual and spent most of the day diving to keep up the pretense that they’d found something. It wasn’t until after dark that Sam, Remi, and Albrecht saw Tibor arrive in an eight-year-old Mercedes sedan. “Is this your car?” Sam asked.
