"I walked through the door to find my six-year-old son suffocating on the floor while my husband stood feet away, entirely unfazed. Then an EMT took one glance at him, drained of color, and whispered, “That man is not who you think he is.”

I went back to the house the next morning under the guise of packing a bag for Leo’s hospital stay. David stayed behind at the hospital, playing the devoted guardian, refusing to leave the waiting room. It gave me exactly two hours.

The house, once my sanctuary, now felt like a tomb. I started in his home office, tearing through files, checking behind paintings, tearing up the rug. Nothing. He was too careful.

Then I remembered the loose floorboard in the basement, the one he claimed was just a foundation quirk and forbade Leo from playing near.

I grabbed a crowbar from the garage and pried the heavy oak board up. Beneath it lay a biometric lockbox. My heart sank. I couldn't crack a fingerprint scanner. But as I stared at it, I remembered David's obsession with routine. I ran upstairs, grabbed a piece of clear scotch tape, and returned to his office desk, carefully lifting a pristine thumbprint from his favorite whiskey glass.

Trembling, I pressed the tape to the scanner. Beep. Click.

The lid sprang open. Inside lay stacks of cash, a passport with David’s face but the name 'Arthur Vance,' a collection of driver's licenses, and a small, leather-bound journal. I flipped it open. It was a ledger. Not of money, but of behavior.
