as 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. It's not possible."

"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."

"O.K.," 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
