My husband made dinner that night, and seconds after my son and I finished eating, we collapsed. I forced myself to lie still as if unconscious, and that’s when I heard him whisper on the phone, “It’s done. They’ll both be gone soon.”

My mind went back to that dinner. The tingling on my tongue. The heaviness in my throat. Caleb’s scared eyes. Marcus’s hand on his shoulder.

“I thought I knew my husband,” I said, my voice shaking. “I thought our marriage was broken, maybe. I thought we were unhappy. But I never thought he was planning to kill us.”

I swallowed hard.

“He poisoned me. He poisoned our son. He didn’t do it in anger. He planned it. He studied it. He waited for the perfect night.”

I looked at the jury.

“He didn’t just want us gone. He wanted to erase us.”

Marcus sat at the defense table, staring ahead. Smaller than I remembered, but still arrogant. Still empty.

His lawyer tried to paint him as stressed. Overwhelmed. A man pushed too far by a failing marriage.

But stress does not create fake IDs.

Stress does not fill notebooks with poison calculations.

Stress does not photograph a wife and child through a window while planning their deaths.

Detective Hayes took the stand and laid out the full investigation. Mrs. Whitman testified behind a privacy screen, explaining how she saw Marcus leave, heard voices, and realized something was terribly wrong.

Then came the notebook.

That was the moment the defense crumbled.
