A sharp whistle sounded. Short. Enough to draw the dog's attention. It was the smell that alerted Daryl to the fact he was dealing with another shifter. They all smelled a little off from the animals whose forms they'd taken. Probably had to do with the clothes they wore normally and the human sweat that clinged even after a shift. Whatever it was, it was off and just noticeable enough. And if a shifter was on the same trail as Daryl, they were probably working with Faolan.

He brought a finger to his mouth once he was certain he had the guy's attention. He couldn't tell if they were alone or not, but he'd felt pretty exposed with the whistle and wanted to keep whatever they exchanged as quiet as possible.
