Pendergast strolled back out of the booth and walked across the greensward toward the river itself, pausing at the remains of a ruined sluice gate, now half underwater. 'In the early nineteenth century, the business district would have been two or three blocks out
He led the way back across the promenade and Commerce Avenue, made a left on Court Street and a right on Atchafalaya. 'By the time Dr. Torgensson was forced to move into his final dwelling,' he said, 'St. Michel had become West Baton Rouge. At the time, this neighborhood was a seedy, working-class community between the railroad depot and the ferry landing.'
He turned down another street; consulted the map again; walked a little farther and halted. 'I do believe,' he drawled, 'that we have arrived.'
They had arrived at a small commercial mini-mall. Three buildings sat side by side: a McDonald's; a mobile phone store; and a squat, garishly colored structure named Pappy's Donette Hole--a crusty local chain D'Agosta had seen elsewhere. Two cars were parked in front of Pappy's, and the McDonald's drive-through was doing a brisk business.
'This is
Pendergast nodded, pointing at the cell phone store. '
D'Agosta looked at each of the buildings in turn. His spirits, which had begun to rise during the brief walk, fell again. 'It's like Blast said,' he muttered. 'Totally hopeless.'
Pendergast put his hands in his pockets and strolled up to the mini-mall. He ducked into each of the buildings in turn. D'Agosta, who could not summon the energy to follow, merely stood in the adjoining parking lot and watched. Within five minutes the agent had returned. Saying nothing, he did a slow scan of the horizon, turning almost imperceptibly, until he had carefully scrutinized everything within a three-hundred-sixty-degree radius. Then he did it again, this time stopping about halfway through his scan.
'Take a look at that building, Vincent,' he said.
D'Agosta followed the gesture with his eyes toward the visitor's center they had passed at the beginning of their loop.
'What about it?' D'Agosta asked.
'That was clearly once a water-pumping station. The Gothic Revival style indicates it probably dates back to the original town of St. Michel.' He paused. 'Yes,' he murmured after a moment. 'I'm sure it does.'
D'Agosta waited.
Pendergast turned and pointed in the opposite direction. From this vantage point they had an unobstructed view down to the promenade, the ruined sluice gate, and the wide Mississippi beyond.
'How curious,' Pendergast said. 'This little mini-mall falls
Pendergast broke into a swift walk toward the river again. D'Agosta swung in behind.
Stopping almost at the water's edge, Pendergast bent forward to examine the sluice gate. D'Agosta could see it led to a large stone pipe that was sealed with cement and partially backfilled.
Pendergast straightened up. 'Just as I thought. There was an old aqueduct here.'
'Yeah? So what's it mean?'
'That aqueduct was no doubt abandoned and sealed up when the eastern half of St. Michel crumbled into the river. Remarkable!'
D'Agosta did not share his friend's enthusiasm for historical detail.
'Surely you see it now, Vincent? Torgensson's shack must have been built
D'Agosta shrugged. For the life of him, he didn't see where Pendergast was going.
'In this part of the world it was common--for buildings constructed over the line of an old water pipe or aqueduct, anyway--to cut into an old aqueduct and use it as a basement. It saved a great deal of labor when basements were dug by hand.'
'You think the pipe is still down there--?'
'Exactly. When the shack was built in 1855, they probably used a section of the capped and abandoned tunnel--now quite dry, of course--as the basement. Those old aqueducts were square, not round, and made of mortared stone. The builders merely had to shore up the foundations, construct two brick walls on the sides perpendicular to the existing aqueduct walls, and--voila! Instant basement.'
'And you think that's where we'll find the Black Frame?' D'Agosta asked a little breathlessly. 'In Torgensson's basement?'
'No. Not
'If it's not in the basement, then what's all the excitement about?' Pendergast's coyness could be so maddening sometimes.
'Think: a series of row houses, situated in a line above a preexisting tunnel, each with a basement fashioned from a segment of that tunnel. But, Vincent--think also of the spaces
'So... so you're saying there would be old spaces between the basements.'
'Precisely. Sections of the old aqueduct
