And then, just like that, it was gone. The fire, and the sacrifice, and the dancing primitive people worshipping Something, in their primitive way. The small circle of scientific light was back, bounded by watching cars and the feeling of a Presence, on the night.

Happy shook his head slowly. “Human sacrifice,” he said thickly. “Death and horror and celebration, repeated so often it’s imprinted on this place, like grooves cut in a record. Genius loci, the spirit of the place; a bad place, poisoned by the psychic stain of what happened here . . . Sacrifice, to ensure the sun will rise again, and that spring will follow winter, and that at least some of the babies will live. One life offered up freely for the greater good. In worship to some great Power.”

“But what woke it up, after lying quiet for so long?” said Melody. “There’s always a focal point to every haunting, some single trigger . . .”

“The fools,” said JC. “The bloody fools . . . When the building contractors broke ground here, they must have dug down deep enough to uncover the ancient site. They stopped work and consulted the supermarket bosses, who were afraid that archaeologists might move in and bring operations to a halt, costing them millions. So they had the contractors cover over the disturbed site and built their new car park here anyway.”

“Yeah,” said Happy. “So far, so typical. So?”

“Don’t you get it?” said JC, almost angrily. “First they disturb the energy stored in the old site, the ancient bad place with all its memories of long-forgotten Power. And then they held a big opening ceremony here, made a real celebration of it. Even then, they might have got away with it . . . If an old lady hadn’t died here, killed by a man in a hurry. So—a ceremony, blood and death, calling across the centuries, like to like. A direct link between Past and Present, awakening . . . Something ancient and unspeakably powerful. All it needed to manifest fully was three poor damned fools who thought they knew what they were doing. A telepath, a woman with powerful technology, and a leader who should have known better. It’s us. We did this. We woke it up.”
