Garvey heard movements within the crate. He smiled to himself, remembering stories he had heard of the surrogates' piquant habits. Suddenly there was a high-pitched clanging. It was the standby alarm from the control room. He hurried forward.

It was an emergency broadcast, on all frequencies, directed to Earth and all ships at space. Garvey tuned it in.

"This is Edward Danzer," the radio announced crisply. "I am Chief of the Washington branch of the Federal Bureau of Investigation. You have all heard, on your local newscasts, of the detection and closure of an illegal sexual substitute factory. And you know that all except one of the surrogates have been found. This message is for the man who has that last surrogate, wherever he may be."

Garvey licked his lips nervously and hunched close to the radio. Within the after cabin, the surrogate was still making waking-up noises.

"That man is in danger!" Danzer said. "Serious danger! Our investigation of the molds and forms used in the factory showed us that something strange was going on. Just this morning, one of the factory technicians finally confessed.

"The missing surrogate is not an Earth model!

"I repeat," Danzer barked, "the missing surrogate is not an Earth model! The factory operators had been filling orders for the planet Algol IV. When they ran short of Earth models for humans, they substituted an Algolian model. Since the sale of a surrogate is illegal anyhow, they figured the customer would have no kickback."

Garvey sighed with relief. He had been afraid he had a small dinosaur in the packing case, at the very least.

"Perhaps," Danzer continued, "the holder of the Algolian surrogate does not appreciate his danger yet. It is true, of course, that the Algolians are of the species homo sapiens. It has been established that the two races share a common ancestry in the primeval past. But Algol is different from our Earth.
