After dropping Jessica off at school with a bag of medication, I sat in my car and broke down in tears.
Jessica was so close to being killed.
I told myself I couldn't let this go, and I needed to get justice for Jessica.
I thought it over for a long time. I knew I couldn't confront Mia without evidence. With her flair for drama, she'd never admit to anything.
I needed to catch her in the act.
"I have to stay calm, not give myself away."
I reminded myself sternly.
After mentally preparing myself, I maintained a calm expression as I picked up Jessica from school for dinner.
Though the flames of vengeance burned fiercely within me, I even managed to endure the sneers and jabs from Mia and Sophia at the dinner table.
Finally, nighttime came. I waited until Mia went to the bathroom, then discreetly placed a tiny camera next to the refrigerator.
Afterward, I returned to my room and focused on the live feed on my phone.
At 10:30 PM, I saw Mia enter the kitchen.
She took a carton of milk from the fridge and then pulled a small packet from her pocket. She took out a white pill from the packet and dropped it into a glass, then poured the milk over it.
She put the glass in the microwave to heat it.
