The afternoon sun shone brightly over the quiet suburban neighborhood in Dallas, Texas.
Sarah pulled her car into the long driveway of her husband's luxury family estate.
She adjusted her beige puffer jacket as she stepped out into the crisp air.
Her baby boy, Leo, had been staying with his grandmother for the afternoon.
Sarah felt a strange tightness in her chest as she walked up the stone steps.
She had left work early because a restless feeling would not leave her mind.
Her mother-in-law, Evelyn, had offered to watch little Leo while Sarah finished her meetings.
Evelyn was an elderly woman with sharp blue eyes and a rigid posture.
She came from high society and always insisted on complete control over family matters.
Sarah unlocked the heavy front door and stepped quietly into the front hallway.
The house was silent, except for the faint sound of soft footsteps near the kitchen.
Sarah set her bag on the entry table and moved down the hallway.
She checked her smartphone to see if the nanny camera app was still connected.
The screen flickered for a second before revealing a troubling sight inside the kitchen.
Evelyn was holding Leo while a family maid brought over a small bowl of dark liquid.
Sarah remembered the doctor's strict warnings about Leo's severe food allergies.
Her heart started pounding fast against her ribs as she watched the live video.
Evelyn nodded to the woman, instructing her to feed the baby immediately.
Sarah did not wait another second to react.
She rushed down the hall toward the double glass doors of the kitchen.
