“Christ. What the hell are we up against? First that paddle-boat illusion, now undetectable weapons.”

“I don’t know. Not yet, but I’m going to find out.” She was surprised at her own determination.

“Do you need assistance? It’s a long walk back to the boat.”

“Negative. I don’t think we should join up. Two groups still have a better chance to achieve our objective than one, nothing has changed that.”

“OK, but we’re here if it gets too tough.”

“Thanks. Listen, Murphy, I’m not aiming to stay in this jungle after dark. Hell, we can’t even see them coming at us in the daytime.”

“Now that sounds like the first piece of sensible advice you’ve given today.”

She referred to her neural nanonics. “There are another seven hours of daylight left. I suggest we try and rendezvous back at the Isakore in six hours from now. If we haven’t captured a hostile, or found out what the hell is going down around here, we can review the situation then.”

“I concur.”

“Jenny,” Dean called with soft urgency.

“Call you back,” she told Murphy.

They had reached the edge of the barrage zone. Not even the tree stumps had survived here. Craters overlapped, producing a crumpled landscape of unstable cones and holes; crooked brown roots poked up into the sky from most of the denuded soil slopes. Long strands of steam, like airborne worms, wound slowly around the crumbling protrusions, sliding into the holes to pool at the bottom.

Over on the far side she watched three men emerging from the craters, scrambling sluggishly for solid ground. They helped each other along, wriggling on their bellies when the slippery loam proved impossible to stand on.

Jenny watched their progress in the same kind of bewildered daze which had engulfed her as the fantastical paddle-steamer sailed down the river.

The men reached level ground sixty metres away from the ESA team, and stood up. Two were recognizable colonist types: dungarees, thick cotton work shirts, and woolly beards. The third was dressed in some kind of antique khaki uniform: baggy trousers, calves bound up by strips of yellowish cloth; a brown leather belt round his waist sporting a polished pistol holster; a hemispherical metal hat with a five-centimetre rim.
