Her name was Mavis. She was in all the family pictures: us on the front steps, me with a skinned knee and her with an ice cream cone; the pool with the bright orange water wings on our arms and our skin two shades lighter for all the sunscreen; the ballet recital where I was the swan and she was in a cast.
When they arrested her, it was on a spellcraft violation. Something technical, a harassment tactic. I don't know what happened after.
She started fading from our pictures a week later. That's how we knew she was gone.
