At once I halt in my tracks and turn around. Just a few paces away, Midnight hovers above the coyote that was just a second ago giving pursuit. A slow steady beat of Middie's wings keeps her head and forehooves upright, while her hind legs hang down, looking ready for a kick if need be. But the coyote lays still on its side in the sand, whimpering faintly to accompany its ragged, shallow breathing.  Blood drips from its snout, leaving a small pool of crimson to sink and meld with the copper sand.
