The sun was still slightly above the horizon when the plane touched down at JFK jetport. Lou had been there once before and recognized it from the air. But their jet taxied to a far corner of the sprawling field, and stopped in front of a waiting helicopter.

The marshal was awake now, and giving orders again. Lou glared at him, but followed his directions. They went out of the jet, across a few meters of cracked grass-invaded cement, and up into the plastic bubble of the copter. Lou sat down on the back bench behind the empty pilot’s seat. The marshal climbed in heavily and sat beside him, wheezing slightly.

Over the whir of the whizzing rotors and the nasal hum of the electric motor, Lou shouted:

“Just where are you taking me? What’s this all about?”

The marshal shook his head, slammed the canopy hatch shut, and reached between the two front seats to punch a button on the control panel. The motor hummed louder and the copter jerked up off the ground.

By the time the helicopter flashed over the skyline of Manhattan, Lou was furious.

“Why won’t you tell me anything?” he shouted at the marshal, sitting beside him on the back bench. He was leaning back with his burly arms folded across his chest and his sleepy eyes half closed.

“Listen, kid, the phone woke me up at four this morning. I had to race out to the jetport and fly to Albuquerque. I spent half the day waiting for you at that silly glider race. Then I drove to your apartment, and you didn’t show up there. Then I went to your lab. Know what my wife and kids are doing right now? They’re sitting home, wondering whether I’m dead or alive and why we’re not all out on the picnic we planned. Know how many picnics we can afford, on a marshal’s pay? Been planning this one all year—had a spot in the upstate park reserved months ago. Now it’s going to waste while I hotfoot all across the country after you. So don’t ask questions, understand?”
