"The car was hitting it up at about a hundred and ten by this time, and accelerating all the time. But the souped-up squad car was coming on fast, too, and it was quite a chase. Luckily, there weren't many cars on the road. Somebody could have been killed, Malone." "Like the driver of the Cadillac," Malone ventured. Burris looked pained. "Not exactly," he said. "Because the car hit the 125th Street exit like a bomb. It swerved right, just as though it were going to take the exit and head off somewhere, but it was going much too fast by that time. There just wasn't any way to maneuver. The Cadillac hit the embankment, flipped over the edge, and smashed. It caught fire almost at once. Of course the prowl car braked fast and went down the exit after it. But there wasn't anything to do." "That's what I said," Malone said. "The driver of the Cadillac was killed. In a fire like that--" "Don't jump to conclusions, Malone," Burris said. "Wait. When the prowl car boys got to the scene, there was no sign of anybody in the car. Nobody at all." "In the heat of those flames--" Malone began. "Not enough heat, and not enough time," Burris said. "A human body couldn't have been destroyed in just a few minutes, not that completely. Some of the car's metal was melted, sure; but there would have been traces of anybody who'd been in the car. Nice, big, easily seen traces. And there weren't any. No corpse, no remains, no nothing." Malone let that stew in his mind for a few seconds. "But the cops said--" "Whatever the cops said," Burris snapped, "there was nobody at all in that Cadillac when it went off the embankment." "Now, wait a minute," Malone said. "Here's a car with a driver who appears and disappears practically at will. Sometimes he's there and sometimes he's not there." "Ah," Burris said. "That's why I have another explanation." Malone shifted his feet. Maybe there _was_ another explanation. But, he told himself, it would have to be a good one. "Nobody expects a car to drive itself down a highway," Burris said. "That's right," Malone said. "That's why it's all impossible." "So," Burris said, "it would be a natural hallucination--or illusion, anyhow--for somebody to imagine he did see a driver when there wasn't any." "Okay," Malone said. "There wasn't any driver. So the car couldn't have gone anywhere. So the New York police force is lying to us. It's a good explanation, but it--" "They aren't lying," Burris said. "Why should they? I'm thinking of something else." He stopped, his eyes bright as he leaned across the desk toward Malone. "Do I get three guesses?" Malone said. Burris ignored him. "Frankly," he said, "I've got a hunch that the whole thing was done with remote control. Somewhere in that car was a very cleverly concealed device that was capable of running the Cadillac from a distance." It did sound plausible, Malone thought. "Did the prowl car boys find any traces of it when they examined the wreckage?" he said.
