On the fifth day, she approached me near the vending machines and began talking about our parents’ will in a tone that felt disturbingly practical.

When I challenged her, she deflected, insisting she was only trying to be realistic, but her composure cracked when I pushed further.

At that moment, my phone buzzed with a message containing a screenshot of a real estate listing for my parents’ house, labeled as a prime opportunity for cash buyers.

The timing was impossible to ignore.

Miles later confirmed that the hardware store cashier remembered Brittany purchasing the items listed on the receipt.

That same evening, I overheard Brittany speaking with her fiancé, Evan Caldwell, in a quiet hallway.

“She is getting suspicious,” Brittany whispered.

Evan replied, “It does not matter if we control the paperwork, once they are gone everything moves quickly.”

The words froze my blood.

Shortly after, the detective confirmed that Brittany’s supposed retreat photos were stock images taken from the internet.

The lie collapsed instantly.

PART 5

When my father finally regained consciousness, it was gradual and quiet, his eyes opening slowly as if returning from somewhere distant.

When I explained what had happened, he immediately frowned and whispered, “The alarms.”

When I told him they had not worked, something shifted in his expression.

“Kara,” he said weakly, though in this version it was Brittany, and the name carried weight like a revelation.

He described her visit the night before, mentioning that she had claimed to fix the thermostat and that he had heard sounds near the hallway.

He had seen her holding something white.

That testimony removed any remaining doubt.

Miles compiled all the evidence, including the footage, receipts, and system logs, and handed everything to the detective.

The thermostat data showed Brittany accessing the system late at night, disabling safety alerts, and adjusting airflow settings in a precise sequence.

She had controlled the environment.

Not just tampered with it.

When Brittany was arrested, she looked at me with anger rather than regret and said, “This was not supposed to happen like this, you always ruin everything.”

Her words confirmed everything.
