Firestone Hot Springs Good Sleep, a Bath and a Glass of Wine [M]

They're on different sides, so your post works perfectly. :D

I don't think he'd catch up with her, so you can say she gets away. :)

She didn't even turn until his chest hit the water, causing a loud splash even as the impact seemed to instantaneously bruise his ribs. As he churned across the river, Ellie bolted, getting a significant head start. By the time Peregrine leaped onto the bank, she was several hundred yards ahead of him. His legs felt a little rubbery from the rapid swim and his lungs already hurt but he gave chase anyway. It was a matter of principle. Even if he couldn't catch her after all, he would scare the disrespectful, cowardly bitch straight.

Paws pounding and chest heaving—it was already getting a bit of a stitch, which made him grimace—Peregrine somehow managed a short burst of words, shot like bullets and delivered with a heavy dose of angry savagery. "You'd better run, you stupid cunt! If I catch you, I'll kill you!" He said nothing else, putting all of his remaining energy into the pursuit.
