Molly black magic

Mouse sat down between me and Molly, watching her intently.
Molly smiled at the dog and reached down to pet him.
Mouse tensed up, and a low rumbling came from his chest. Molly moved her hand toward him again, and my dog's chest suddenly rumbled with a deep and warning growl.
The last time Mouse had growled at anything-for that matter, made much noise at all-it had been a crazed sorcerer who made fair headway toward eviscerating me, and summoned a twenty-foot-long demon cobra to kill my dog. Mouse killed it instead. Then, at my command, Mouse killed the sorcerer, too.
And now he was growling at Molly.
"Be polite," I told him firmly. "She's a friend."
Mouse gave me a look and then fell quiet again. He sat calmly as Molly let him sniff her hand and scratch at his ears, but his wary body language didn't change.
"When did you get a dog?" Molly asked.
Mouse was spooked, though not the way he was when serious bad guys were around. Interesting. I kept my tone neutral. "Couple years ago. His name is Mouse."
