They came around a point and into view of a tiny inlet, just a kerf in the land where some small creek probably spilled into it. On the IR, the boundary between water and land was a solid, squirming mass of white. Around its edges Rufus was able to pick out individual silhouettes with the familiar dished head shape of Sus domesticus . In the open rangeland of Texas this herd would have been considered large, but not astonishing. Certainly more than twenty animals but not more than thirty. Here on the lake, surrounded by houses, it seemed pretty huge. Rufus was gaping at it, beginning to doubt the evidence of his senses, trying to work out how they had reached this place and where they were getting food, when one silhouette much larger than the others hove up out of the mass and waddled to higher ground.
