A pair of headlights rounded the nearby corner. Bill looked up. "That's the prowl car," he announced, and went over to meet it.

The driver was a solidly-built little man with the face of a Pekingese. His partner, a tall man who looked as if he'd have been much more comfortable in a ten-gallon Stetson instead of the regulation blue cap, leaned out at Bill, Sam and Malone.

"What's the trouble here?" he said in a harsh, high voice.

"No trouble," Bill said, and went over to the car. He began talking to the two cops inside in a low, urgent voice. Meanwhile, Sam got his arm around Malone and began pulling him away from the lamp post.

Malone was a little unwilling to let go, at first. But Sam was stronger than he looked. He convoyed the FBI agent carefully to the rear door of the prowl car, opened it and levered Malone gently to a seat inside, just as Bill said: "So with the cut and all, we figured he ought to go over to St. Vincent's. You people were already on the way, so we didn't bother with ambulances."

The driver snorted. "Next time you want taxi service," he said, "you just call us up. What do you think, a prowl car's an easy life?"

"Easier than doing a beat," Bill said mournfully. "And anyway," he added in a low, penetrating whisper, "the guy's FBI."

"So the FBI's got all kinds of equipment," the driver said. "The latest. Why don't he whistle up a helicopter or a jet?" Then, apparently deciding that further invective would get him nowhere, he settled back in his seat, said: "Aah, forget it," and started the car with a small but perceptible jerk.

Malone decided not to get into the argument. He was tired, and it was late. He rested his head on the

back seat and tried to relax, but all he could do was think about red Cadillacs.
