I pretended to fly to Canada after suspecting the housekeeper was doing something terrible to my daughters whenever I was away. Instead, I secretly returned home and turned on the hidden cameras.

Then she added something else.

“She’s also turning the girls against you.”

A cold feeling moved through me.

“What do you mean?”

“They’re far too attached to her,” Chloe whispered.

“When you walk into a room, they become quiet. But when Marisol appears, they immediately run to her.”

She touched my hand.

“That woman knows everything about this family. Our schedules. Our habits. Private conversations.”

Then she said,

“It’s always the quiet ones you should watch.”

I didn’t want to believe her.

But suspicion has a way of changing the meaning of ordinary things.

Once someone gives you a reason to doubt, suddenly every harmless detail starts looking different.

Over the next few days, I began watching Marisol more carefully.

She knew exactly how Sofia liked her breakfast.

Valeria often waited by the window for Marisol to finish working so they could read together.

Whenever Marisol entered a room, both girls seemed to relax.

Those were things I had once considered evidence that she genuinely cared about them.

Now I found myself wondering whether Chloe was right.

That was why I invented the Toronto trip.

Three months earlier, I had upgraded the estate’s entire security system.

More than thirty concealed high-definition cameras covered the hallways, living spaces, kitchen, garden, entrances, and other common areas.
