"I figure," rumbled the sergeant, "they're a lot like delinks. A cop can figure how they think, but they can't figure how a cop thinks."

"Such as?" asked the skipper.

"They can't understand anybody not tryin' to be important," said Sergeant Madden. "It baffles 'em."

"What's that got to do with the people on the Cerberus?" demanded the skipper. "It's our job to get them and the Cerberus back on the way to port!"

"I know!" conceded Sergeant Madden, "and the girl my son Timmy's going to marry is one of them. But I don't think we'll have much trouble. Have you got any multipoly plastic on the Aldeb?"

The skipper nodded, blankly. Multipoly plastic is a substance as anomalous as its name. It is a multiple polymer of something-or-other which stretches very accommodatingly to a surprising expanse, and then suddenly stops stretching. When it stops, it has a high and obstinate tensile strength. All ships carry it for temporary repairs, because it will seal off anything. A one-mill thickness will hold fifteen pounds pressure. Ships have been known to come down for landing with bubbles of multipoly glistening out of holes in their hulls. A salvage ship, especially, would carry an ample supply. A minor convenience in its use is the fact that a detonator-cap set off at any part of it starts a wave of disintegration which is too slow to be an explosion and cleans up the mess made in its application.

"Naturally I've got it," said the skipper. "What do you want with it?"

Sergeant Madden told him. Painfully. Painstakingly.

"The tough part," said the skipper, "is making 'em go out an ejector tube. But I've got fourteen good men. Give me two hours for the first batch. We'll make up the second while you're placing them."

Sergeant Madden nodded.
