Not that he begrudged Boyd his fun. It was nice that one of them was enjoying himself, anyway.

It was just that Malone was beginning to get fidgety. He needed to be doing something--even if it were only taking a walk.

So he took a walk, and ended up, to his own surprise, downtown near Greenwich Village.

And then he'd been bopped on the head.

IV.

The patrol car pulled up in front of St. Vincent's Hospital and one of the cops helped Malone into the Emergency Receiving Room. He didn't feel as bad as he had a few minutes before. The motion of the car hadn't helped any, but his head seemed to be knitting a little, and his legs were a little steadier. True, he didn't feel one hundred per cent healthy, but he was beginning to think he might live, after all. And while the doctor was bandaging his head a spirit of new life began to fill the FBI agent.

He was no longer morose and undirected. He had a purpose in life, and that purpose filled him with cold determination. He was going to find the robot-operated car--or whatever it turned out to be.

The doctor, Malone noticed, was whistling "Greensleaves" under his breath as he worked. That, he supposed, was the influence of the bohemian folk singers of Greenwich Village. But he put the noise resolutely out of his mind and concentrated on the red Cadillac.

It was one thing to think about a robot car, miles away, doing something or other to somebody you'd never heard of before. That was just theoretical, a case for solution, nothing but an ordinary job.

But when the car stepped up and bopped Malone himself on the head, it became a personal matter. Now Malone had more than a job to contend with. Now he was thinking about revenge.

He told himself: _No car in the world--not even a Cadillac--can get away with beaning Kenneth J. Malone!_

Malone was not quite certain that he agreed with Burris' idea of a self-operating car, but at least it was something to work on. A car that could reach out, crown an investigator and then drive off humming something innocent under its breath was certainly a unique and dangerous machine within the meaning of the act. Of course, there were problems attendant on this view of things; for one thing, Malone couldn't quite see how the car could have beaned him when he was ten feet away from it.

But that was, he told himself uncomfortably, a minor point. He could deal with it when he felt a little better.

The important thing was the car itself. Malone jerked a little under the doctors calm hands, and swore subvocally.

"Hold still," the doctor said. "Don't go wiggling your head around that way. Just wait quietly until the demijel sets."

Obediently, Malone froze. There was a crick in his neck, but he decided he could stand it. "My head still hurts," he said accusingly.

"Sure it still hurts," the doctor agreed.

"But you--"

"What did you expect?" the doctor said. "Even an FBI agent isn't immune to blackjacks, you know." He resumed his work on Malone's skull.

"Blackjacks?" Malone said. "What blackjacks?"

"The ones that hit you," the doctor said. "Or the one, anyhow."

Malone blinked. Somehow, though he could manage a fuzzy picture of a car reaching out to hit him, the introduction of a blackjack into this imaginative effort confused things a little. But he resolutely ignored it.

[Ill.u.s.tration]

"The bruise is just the right size and shape," the doctor said. "And that cut on your head comes from the seams on the leather casing."

"You're sure?" Malone said doubtfully. It did seem as if a car had a lot more dangerous weapons around, without resorting to blackjacks. If it had really wanted to damage him, why hadn't it hit him with the engine block?

"I'm sure," the doctor said. "I've worked in Emergency in this hospital long enough to recognize a blackjack wound."

That was a disturbing idea, in a way. It gave a new color to Malone's reflection on Greenwich Villagers. Maybe things had changed since he'd heard about them. Maybe the blackjack had supplanted the guitar. But that wasn't the important thing.

The fact that it had been a blackjack that had hit him was important. It was vital, as a matter of fact. Malone knew that perfectly well. It was a key fact in the case he was investigating.

The only trouble was that he didn't see what, if anything, it meant.

The doctor stepped back and regarded Malone's head with something like pride. "There," he said. "You'll be all right now."

"When?" Malone said.

"You're not badly hurt," the doctor said reprovingly. "You've got a slight concussion, that's all."

"A concussion?"

"Sure," the doctor said. "But it isn't serious. Just take these pills--one every two hours until they're gone--and you'll be rid of any effects within twenty-four hours." He went to a cabinet, fiddled around for a minute and came back with a small bottle containing six orange pills. They looked very large and threatening.

"Fine," Malone said doubtfully.

"You'll be all right," the doctor said, giving Malone a cheerful, confident grin. "Nothing at all to worry about." He loaded a hypojet and blasted something through the skin of Malone's upper arm. Malone swallowed hard. He knew perfectly well that he hadn't felt a thing, but he couldn't quite make himself believe it.

"That'll take care of you for tonight," the doctor said. "Get some sleep and start in on the pills when you wake up, O.K.?"

"O.K.," Malone said. It was going to make waking up something less than a pleasure, but he wanted to get well, didn't he?

Of course he did. If that Cadillac thought it was going to beat him....

"You can stand up now," the doctor said.

"O.K.," Malone said, trying it. "Thanks, doctor. I--"

There was a knock at the door. The doctor jerked his head around.

"Who's that?" he said.

"Me," a ba.s.s voice said, unhelpfully.

The Emergency Room door opened a crack and a face peered in. It took Malone a second to recognize Bill, the waffle-faced cop who had picked him up next to the lamp post three years or so before. "Long time no see," Malone said at random.

"What?" Bill said, and opened the door wider. He came in and closed it behind him. "It's O.K., Doc," he said to the attendant. "I'm a cop."

"Been hurt?" the doctor said.
