He wore an old T-shirt with the sleeves torn off, and his lean muscles moved under coppery skin. He had a tattoo on the inside of his forearm--a small one that looked like raven wings. When he turned around, I caught the faint edge of another tattoo on his shoulder peeking from under his shirt.
He glanced over, like he'd sensed me looking. When I didn't turn away, he grinned and mouthed something I didn't catch, probably didn't want to.
