I installed a hidden camera in my room to get proof that my mother-in-law was rummaging through and taking my jewelry, but I never imagined that I would witness the even more terrifying secret that my husband had been hiding for ten years.

But the worst revelation was still coming.

Mark stood up, glanced around nervously, and opened a box I had never seen before.

Inside were piles of receipts:

Rent payments for another woman.

Hospital bills for an eight-year-old child.

Fees for private tutoring.

And a birth certificate.

The camera zoomed in close enough for me to read:

Father’s name: Mark.

My phone nearly slipped from my hand.
