I understood how hard it was to raise a child alone, so I offered to cover her daughter's tuition for all four years.

Georgette was so moved she burst into tears. She gripped my hands, thanking me over and over, swearing she'd repay my kindness someday.

But starting last month, things changed.

I came home one day and found Cora Fox sitting in my living room.

I had no idea why she was there. Georgette pulled me aside and whispered an explanation:

"Miss Henson, my daughter has nowhere to go on weekends. I haven't seen her in so long, so I told her she could stay for a couple of days."

I nodded and let it go. The house had plenty of rooms. Letting a mother and daughter spend some time together wasn't a big deal.

But gradually, something started to feel off.

The "couple of days" turned into a standing appointment, every single weekend without fail. Every Friday evening, Cora showed up at my door like clockwork and didn't leave until Monday morning.

At first, she just liked posing for photos in the living room and posting them online, showing off to her classmates about living in a mansion. I could understand that. Everyone wants to look good in front of other people.
