After I walked my 7-year-old daughter to her mom’s car for weekend visitation, she slipped a note into my pocket. ‘Don’t read until I’m gone.’ I waited five minutes and opened it. ‘Dad, check under your bed tonight. Grandma hid something there yesterday.’ I rushed inside the house and lifted the mattress. What I found made me call 911 immediately.

ma’s drawings were taped. Butterflies. Rainbows. Stick figures of the two of us holding hands.

My phone buzzed again. Joseph.

Thomas, you need to see something. I’ve been digging deeper into Bernice’s finances. She’s been moving money. Lots of it. Through shell companies, offshore accounts. This is bigger than just drugs. Man, I think she’s laundering money.

Send me everything you found, I replied.

Already did. Check your email.

I opened my laptop. Joseph had been thorough. Bank records pulled from public filings, property transfers, business licenses. Bernice Wright had her fingers in a dozen different enterprises. All of them cash-heavy: storage facilities, laundromats, car washes. Classic money-laundering setups. And all of them rented to people with criminal records.

An idea began forming. Dangerous. Possibly illegal. But effective.

If Bernice wanted to play dirty, I could play dirtier. I just needed to be smarter about it.
