She started and he got to his feet. A hardly-noticed discomfort was becoming acute; the speedboat was pitching and rolling quite seriously, for the first time since their escape. "Dirty weather coming up," he said. "We've been too damned lucky so far." He thought, but didn't remark, that there was much to worry about in the fact that there seemed to have been no pursuit. The meager resources of the North American Navy wouldn't be spent on chasing a single minor craft—not if the weather could be counted on to finish her off.
"I thought we were unsinkable?"
"In a way. Seal the boat and she's unsinkable the way a corked bottle is. But the boat's made up of a lot of bits and pieces that go together just so. Pound her for a few hours with waves and the bits and pieces give way. She doesn't sink, but she doesn't steam or steer either. I wish the Syndic had a fleet on the Atlantic."
"Sorry," she said. "The nearest fleet I know of is Mob ore boats on the great lakes and they aren't likely to pick us up."
The sea-search radar pinged and they flew to the screen. "Something at 273 degrees, about eight miles," he said. "It can't be pursuit. They couldn't have any reason at all to circle around us and come at us from ahead." He strained his eyes into the west and thought he could see a black speck on the gray.
Lee Falcaro tried a pair of binoculars and complained: "These things won't work."
"Not on a rolling, pitching platform they won't—not with an optical lever eight miles long. I don't suppose this boat would have a gyro-stabilized signal glass." He spun the wheel to 180; they staggered and clung as the bow whipped about, searched and steadied on the new course. The mounting waves slammed them broadside-to and the rolling increased. They hardly noticed; their eyes were on the radarscope. Fogged as it was with sea return, they nevertheless could be sure after several minutes that the object had changed course to 135. Charles made a flying guess at her speed, read their own speed off and scribbled for a moment.
He said nothing, but spun the wheel to 225 and went back to the radarscope. The object changed course to 145. Charles scribbled again and said at last, flatly: "They're running collision courses on us. Automatically computed, I suppose, from a radar. We're through."
He spun the wheel to 180 again, and studied the crawling green spark on the radarscope. "This way we give 'em the longest run for their money and can pray for a miracle. The only way we can use our speed to outrun them is to turn around and head back into Government Territory—which isn't what we want. Relax, Lee. Maybe if the weather thickens they'll lose us—no; not with radar."
They sat together on a bunk, wordlessly, for hours while the spray dashed higher and the boat shivered to hammering waves. Briefly they saw the pursuer, three miles off, low, black and ugly, before fog closed in again.
