And the silhouette of a bat fluttered briefly in front of the waning moon.

Franz Weidenreich had been born in Germany in 1873. A completely bald, thickset man, he had made a name for himself as an expert in hematology and osteology. He was currently Visiting Professor at the University of Chicago, but that was coming to an end, and now he was faced with the uncomfortable prospect of having to return to Nazi Germany-something, as a Jew, he desperately wanted to avoid.

And then word came of the sudden death of the Canadian paleontologist Davidson Black. Black had been at the Peking Union Medical College, studying the fragmentary remains of early man being recovered from the limestone quarry at Chou Kou Tien. Weidenreich, who once made a study of Neanderthal bones found in Germany, had read Black's papers in

Nature and Science describing Sinanthropus.

But now, at fifty, Black was as dead as his fossil charges-an unexpected heart attack. And, to Weidenreich's delight, the China Medical Board of the Rockefeller Foundation wanted him to fill Black's post. China was a strange, foreboding place-and tensions between the Chinese and the Japanese were high-but it beat all hell out of returning to Hitler's Germany…

At night, most of the tribe huddled under the rocky overhang or crawled into the damp, smelly recesses of the limestone cave. Without the fire to keep animals away, someone had to stand watch each night, armed with a large branch and a pile of rocks for throwing. Last night, it had been Kart's turn. Everyone had slept well, for Kart was the strongest member of the tribe. They knew they were safe from whatever lurked in the darkness.

When daybreak came, the members of the tribe were astounded. Kart had fallen asleep. They found him lying in the dirt, next to the cold, black pit where their fire had once been. And on Kart's neck there were two small red-rimmed holes, staring up at them like the eyes of the Stranger…

During his work on hematology, Weidenreich had met a remarkable man named Brancusi-gaunt, pale, with disconcertingly sharp canine teeth. Brancusi suffered from a peculiar anemia, which Weidenreich had been unable to cure, and an almost pathological photophobia. Still, the gentleman was cultured and widely read, and Weidenreich had ever since maintained a correspondence with him.

When Weidenreich arrived in Peking, work was still continuing at the quarry. So far, only teeth and fragments of skull had been found. Davidson Black had done a good job of cataloging and describing some of the material, but as Weidenreich went through the specimens he was surprised to discover a small collection of sharp, pointed fossil teeth.

Black had evidently assumed they weren't part of the

Sinanthropus material, as he hadn't included them in his descriptions. And, at first glance, Black's assessment seemed correct-they were far longer than normal human canines, and much more sharply pointed. But, to Weidenreich's eye, the root pattern was possibly hominid. He dropped a letter to his friend Brancusi, half-joking that he'd found Brancusi's great-to-the-nth grandfather in China.

To Weidenreich's infinite surprise, within weeks Brancusi had arrived in Peking.

Each night, another member of the tribe stood watch-and each morning, that member was found unconscious, with a pair of tiny wounds to his neck.

The tribe members were terrified. Soon multiple guards were posted each night, and, for a time, the happenings ceased.

But then something even more unusual happened…

They were hunting deer. It would not be the same, not without fire to cook the meat, but, still, the tribe needed to eat. Four men, Kart included, led the assault. They moved stealthily amongst the tall grasses, tracking a large buck with a giant rack of antlers. The hunters communicated by sign language, carefully coordinating their movements, closing in on the animal from both sides.

Kart raised his right arm, preparing to signal the final attack, when-

– a streak of light brown, slicing through the grass-

– fangs flashing, the roar of the giant cat, the stag bolting away, and then-

– Kart's own scream as the saber-tooth grabbed hold of his thigh and shook him viciously.

The other three hunters ran as fast as they could, desperate to get away. They didn't stop to look back, even when the cat let out the strangest yelp…

That night, the tribe huddled together and sang songs urging Kart's soul a safe trip to heaven.

One of the Chinese laborers found the first skull. Weidenreich was summoned at once. Brancusi still suffered from his photophobia, and apparently had never adjusted to the shift in time zones-he slept during the day. Weidenreich thought about waking him to see this great discovery, but decided against it.

The skull was still partially encased in the limestone muck at the bottom of the cave. It had a thick cranial wall and a beetle brow-definitely a more primitive creature than Neanderthal, probably akin to Solo Man or Java Man…
