“What was it?” Jenny asked.

“Two of them, I think.” Will quickly replayed the memory. It was like a dense black shadow dashing out from behind one of the trees, then it split into two. That was when he fired, and the image jolted. But the black shapes refused to clarify, no matter how many discrimination programs he ran. Definitely too big for sayce, though. And they were moving towards him, using the shaggy treebases for cover.

He felt a glow of admiration, they were good.

“What now?” he datavised. Nobody responded. “What now?” he asked loudly.

“Reconnaissance and evaluation,” said Jenny, who had just realized even short-range datavises were being disrupted. “We’re still not out of that jamming effect.”

There was a silent orange flash above her. The top third of the tree ten metres to her left began to topple over, hinging on a section of trunk that was mostly charred splinters. Just as it reached the horizontal, the rich green plumes at the top caught on fire. They spluttered briefly, belching out a ring of blue-grey smoke, then the fire really caught. Two vennals leapt out, squeaking in pain, their hides badly scorched. Before the whole length of wood crashed down, the plumes were burning with a ferocity which matched the sun.

The horses reared up, whinnying alarm. They were pulled down by boosted muscles.

Jenny realized the animals were rapidly becoming a liability as she clung on to hers. Her neural nanonics reported the suit sensors had detected a maser beam striking the tree, which was what snapped it. But there was no detectable follow-up energy strike to account for the ignition.

Dean’s sensors had also detected the maser beam. He fired a fifty-shot barrage back along the line.

The fallen tree’s tip fizzled out. All that was left was a tapering core of wood and a heap of ash. Blackened ground creepers smouldered in a wide circle around it.
