She handed me a T-shirt. “It’s the shirt David wore yesterday.”
I sniffed it once. No more was needed. Because I knew right away that David had in fact walked away from the barn. His trail might as well have been marked with orange traffic cones

I followed David’s scent as Cassie floated in absolute silence overhead. Her owl’s wings made no sound. Not even to my ears.
<He stopped here,> I said. We were a thousand yards from the barn in the middle of a field. <He morphed. I’m getting a new scent.>
I sniffed carefully at the ground, going around in a circle. <The idiot!> I yelled, suddenly too angry to be dog HAPPY. <He went into that lion morph you hooked him up with.>

I followed the lion scent. We headed across the fields of Cassie’s farm and plunged into woods. Cassie kept pace effortlessly. And after a while a second silent owl and a much noisier hawk caught up to us.

We emerged again from the woods, and now we were close to a major road. On the far side it was a built-up strip: Taco Bell, Mickey D’s, a tire place, a couple of gas stations, and a Holiday Inn.
I sniffed the ground again. <He demorphed here.> I trotted forward closer to the road, closer to the cars blazing past at sixty miles an hour. <Here he morphed again. The golden eagle.>
I took a deep breath. I had a bad feeling about this. I began to demorph. I wanted to be able to look around as a human to see what David had seen.
