Vrooms, Brooms, & Heirlooms

The last time witchy car mechanic Victoria Fox did magic, she nearly blew up half a street. Oops. No more magic for her, but is a witch who doesn't do magic still a witch?
Well, she does have a kitty familiar named Professor Studmuffin Salvitore III. She also has a knack for inviting magical trouble to her shop's doorstep.
Like her business rival who shows up and offers her a deal. A tempting deal, but she shuts the door in his face anyway. Moments later, his star employee drops dead.
All roads lead to Victoria as the murderer. The problem? She didn't do it. The other problem? Almost no one believes her.
It's now up to her and her kitty familiar to prove she's innocent. Tiptoeing closer to the truth could put them both in danger though.

And it might just take a lead paw on the gas pedal to get them out.
