Mouse suddenly stopped in his tracks. Me too. I didn’t rubberneck around. Instead I focused on the dog. Mouse’s ears twitched like individual radar dishes. His nose quivered. One paw came up off the ground, but the dog only looked around him uncertainly. “Lassie would have smelled something,” I told him. “She would have given a clear, concise warning. One bark for gruffs, two barks for Nickelheads.” Mouse gave me a reproachful glance, put his paw back down, and sneezed.
