"What altitude will you fly?"
"Depends on the focal lenses. Altitude is computed mathematically and optically. We're set to make our run at ten thousand feet."
The view of the valley from above was heady. The landscape unfurled and spread to the horizons, crisp and green, crowned by spring clouds. From five thousand feet the river took on the shape of a huge python crawling through the hills, with low islands sometimes dotting the channel like stepping-stones in a small stream. A vineyard country here, and an orchard land, broken by an occasional dairy farm.
When the altimeter read ten thousand, Westler made a sweeping turn to slightly west of north. The De Soto crept beneath, looking like a tiny model in a diorama.
"Cameras are rolling," Westler announced.
"You make it sound like a movie production," said Pitt.
"Almost. Each picture overlaps the next by sixty percent. That way, one particular object will show up twice at slightly different angles with varied highlights. You can detect things that are invisible from ground level, remnants of man-made disturbances hundreds or even thousands of years old."
Pitt could see very clearly the scar of the track bed. Then it abruptly stopped and vanished into a field of alfalfa. He pointed downward.
"Suppose the target is completely obliterated?"
Westler peered through the windshield and nodded. "Okay, there's a case in point. When the land over the area of interest was used for agriculture, the vegetation will assume a subtle color difference due to elements foreign to the native soil composition. The change might be missed by the human eye, but the camera optics and enhanced color tone in the film will exaggerate features in the earth beyond reality."
In no time at all, it seemed to Pitt, they were approaching the southern outskirts of New York State's capital. He gazed down at the oceangoing cargo ships docked at the port of Albany. Acres of railroad tracks fanned out from the storage warehouses like a giant spider's web. Here the old railbed disappeared for good under the heavy foot of modern development. "Let's make another run," said Pitt.
"Coming around," acknowledged Westler.
Five more times they swept the fading New York & Quebec Northern tracks, but the faint, fragile line through the countryside still looked solitary, undivided by discernible offshoots.
Unless the cameras spotted something he couldn't detect, the only hope he had of finding the Manhattan Limited was Heidi Milligan.
The maps had vanished from the portfolio in the railroad museum, and Heidi had no doubt who had stolen them.
Shaw had returned to the hotel later that night, and they had made fluid and gentle love until early morning. But when she awoke, he was gone. Too late she realized that he had listened in on her conversation with Admiral Sandecker. More than once, during their lovemaking, she had thought of Pitt.
It was very different with him. Pitt's style was consuming and savage and impelled her to respond with savage intensity. Their time in bed had been a competition, a tournament that she never won. Pitt had drowned her, left her floating in a haze of exhausted defeat. Deep down it galled her independent ego and her mind refused to accept his superiority, and yet her body hungered for it with sinful abandon.
With Shaw the act was tender and almost respectful, and she could control her responses. Together they nurtured each other; apart they were like two gladiators circling, scheming for an opening to defeat the other. Pitt always left her spent and with a feeling she'd been used. Shaw was using her too, only for a different purpose, but strangely it didn't seem to matter. She longed to come back to him like someone returning from a stormy voyage.
She sat back in a chair in the library room of the museum and closed her eyes. Shaw thought he had forced her into a dead end by stripping the records. But there were other sources of railroad lore, other archives, private collections or historical societies. Shaw knew she could not afford the time-consuming journeys to check them out. So now she had to think of another avenue to explore. And what Shaw couldn't know, couldn't project in his scheming mind, was that she wasn't trapped at all.
"Okay, Mr. Smart-Ass," she muttered to the silent bookshelves, "here's where you get yours."
She called over the yawning curator, who was still grumbling about inconsiderate FBI agents.
"I'd like to see your old dispatch records and logbooks."
He nodded cordially. "We have cataloged samplings of old dispatch material. Don't have them all, of course. Too voluminous to store. Just tell me what you want and I'll be happy to search it out for you."
Heidi told him, and by lunchtime she had found what she was looking for.
Heidi stepped off the plane at the Albany airport at four o'clock in the afternoon. Giordino was there waiting for her. She brushed off an offer of a wheelchair and insisted on walking on her crutches to the car.
"How are things going?" she asked as Giordino pulled the car into traffic and turned south.
"Doesn't look encouraging. Pitt was poring over aerial photographs when I left the boat. No trace of a branch track showed up anywhere."
"I think I've found something."
"We could damn well use a piece of luck, for a change," Giordino muttered.
"You don't sound enthusiastic."
