"Do you think the secret lab is here on the farm?" asked Pitt.
"We don't know," replied Kelly. "When we were certain Dad had left the farm on business or research trips, Josh and I looked everywhere, but never found a clue to its location."
"What was Dr. Egan researching when he died?"
Thomas shrugged helplessly. "I have no idea. He refused to take me into his confidence. He only said it would revolutionize science and technology."
"You were his closest friend," said Giordino. "It's odd that he never confided in you."
"You'd have to have known Elmore. He was two people. One minute the absentminded but lovable father and friend. The next, a paranoid master engineer who trusted no one, not even those closest to him."
"Did he ever take time for pleasure?" inquired Pitt.
Josh and Kelly looked at each other.
"He was incredibly passionate about researching the Vikings," said Thomas.
"He was also a dedicated fan of Jules Verne," added Kelly. "He read his works over and over."
Pitt motioned around the laboratory. "I see no indication of any such passions."
Kelly laughed. "We haven't shown you his library."
"I'd like to see it."
"It's in a separate building beside the house overlooking the river. Dad built it almost twenty years ago. It was his home away from home, his sanctuary from the pressures of his work."
The building that housed Egan's study was made of stone and appeared to be designed after an eighteenth-century grain mill. Slate covered the roof, and ivy rose on the rock walls. The only admission to modern convenience were the skylights in the roof. Thomas used a large, old-fashioned key to unlock the thick oak door.
The interior of the library was what Pitt had imagined. The rows of mahogany bookshelves and the paneled walls oozed finesse and refinement. The big overstaffed chairs and couch were leather, and the desk, still littered with research papers, was a huge rosewood roll-top. The ambience smothered the visitors with comfort and solace. This library must have fit Egan like a snug, well-worn glove, Pitt thought. It was an ideal setting in which to conduct research.
He walked along the bookshelves that ran from floor to ceiling. A ladder with wheels on its upper frames moved along a track, enabling Egan to reach the top shelves. Paintings of Viking ships hung on the only open wall. On a table below the paintings sat a model of a submarine nearly four feet in length. Pitt guessed the scale at a quarter of an inch to the foot. As a marine engineer himself, Pitt studied the model closely, noting the exacting craftsmanship. The boat was rounded on the ends, with portholes along the sides and a small tower that sat toward the bow. The propeller's blades were shaped more like paddles than the curved tips of modern designs.
Pitt had never seen a craft quite like it. The only comparison he could think of was a diagram of a submarine he'd studied once that had been built by the Confederates during the Civil War.
The brass plaque on the base beneath the model read, Nautilus. Seventy meters in length with an 8-meter beam. Launched 1863.
"A beautiful model," said Pitt. "Captain Nemo's submarine, isn't it? From Twenty Thousand Leagues under the Sea?"
"Dad designed it from an etching in the original book and found a master model builder by the name of Fred Torneau to construct it."
"Classic work," said Giordino admiringly.
Pitt continued his tour, examining the titles of the books on the shelves. They all covered the Viking era from 793 to 1450 A.D. One entire section was devoted to the runic alphabets used by the Germanic and Norse people from the third to the thirteenth centuries.
Kelly watched Pitt's interest in the books and came up, holding his arm. "Dad became expert at translating the characters found on rune stones throughout the country."
"He believed the Vikings came this far south?"
She nodded. "He was convinced. When I was little, he dragged mother and me around half the midwestern states in an old camper while he copied and studied every rune stone he could find."
"Couldn't have been a large number," said Giordino.
"He found and recorded over thirty-five stones with ancient runic alphabets." She paused and pointed to one entire shelf of binders and notebooks. "It's all right there."
"Did he ever intend to publish his findings?" asked Giordino.
"Not as far as I knew. About ten years ago, it was as if a light switch had been turned off. He suddenly lost all interest in his Viking research."
