"Patrol-ship!"

"Hurry!"

The ship, suddenly exposing its lights, was perfectly visible above us. Five thousand feet up, possibly. A tiny silver bird in the moonlight: but even with the naked eye I could see by its light pattern that it was the official Porto Rican patrol-liner. It saw us down here: recognized this bandit flyer, no doubt.

And it was coming down!

There was a confusion as the bandits rushed aboard. The patrol was dropping in a swift spiral. I watched tensely, holding Jetta, with the turmoil of the embarking bandits around me. Gutierrez stood with levelled weapon.

"They have not moved, Commander."

De Boer was here. The treasure was aboard.

"Ready, Hans. Lift us."

The landing portes clanged as they closed. Hans shoved at his switches. I heard the helicopter engines thumping. A vertical lift: there was no space in this rocky defile for any horizontal take-away.

He was very calm, this De Boer. He sat in a chair at a control-bank of instruments unfamiliar to me.
