She glanced back over her shoulder and caught her breath at a swift blur of movement, and stopped in her tracks. An enormous lioness, twice as large as any feline who would populate savannas far to the south in a much later age, had been stalking the herd. The girl stifled a scream as the monstrous cat vaulted for a wild cow.

In a flurry of snarling fangs and savage claws, the giant lioness wrestled the massive aurochs to the ground. With a crunch of powerful jaws, the terrified bawl of the bovine was cut short as the huge carnivore tore out its throat. Spurting blood stained the muzzle of the four-legged hunter and sprayed her tawny fur with crimson. The aurochs’s legs jerked spasmodically even as the lioness ripped open its stomach and tore out a chunk of warm, red meat.

Stark terror charged through the girl. She fled in wild panic, carefully watched by another of the great cats. The child had stumbled into the territory of cave lions. Normally the large felines would have disdained so small a creature as a five-year-old human as prey, preferring a robust aurochs, oversize bison, or giant deer to satisfy the needs of a pride of hungry cave lions. But the fleeing child was approaching much too near to the cave that housed a pair of mewling newborn cubs.

Left to guard the young while the lioness hunted, the shaggy-maned lion roared in warning. The girl jerked her head up and gasped at the gigantic cat crouched on a ledge, ready to spring. She screamed, slid to a stop, falling and scraping her leg in the loose gravel near the wall, and scrambled to turn around. Spurred on by even greater fear, she ran back the way she had come.

The cave lion leaped with languid ease, confident of his ability to catch the small interloper who dared to broach the sanctity of the cave nursery. He was in no hurry-she moved slowly compared with his fluid speed-and he was in the mood for a game of cat and mouse.
