"You did?" Cal's finger went around the trigger of the gun.
"Yeah. I was following her but I didn't know she knew it until she yelled."
"Oh." Cal kept his finger on the trigger. "Why were you following her?"
"Hell, don't be stupid!" Zen exploded. "Why would any man follow a woman like that?"
A trace of a grin went across the wolf face at this answer. Cal licked his lips. This was an answer he understood. "I don't blame you for that. But why was she coming up here?"
