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.”

I forced air into my lungs.

“He poisoned us,” I whispered. “He’s been planning it. He was going to kill us.”

The officer’s face darkened. He rose and signaled to someone behind him.

“Stay here. We’ll handle it.”

I held Caleb so tightly I was afraid I might hurt him.

Outside the bathroom, the house became a storm of police voices. Then I heard a woman’s voice, cool and controlled.

“The poison traces in the food are conclusive. Pesticide concentrate. Enough to kill two people quietly.”

My stomach dropped.

Marcus hadn’t snapped.

He had calculated.

He had meant for us to die slowly, quietly, in our own home.

And the only reason we were alive was because of Mrs. Whitman.

The neighbor I barely knew.

The quiet woman across the street who kept to herself, watched everything, and apparently had seen enough. She had noticed Marcus acting strangely. She had heard part of his conversation. She had seen us collapse.

And instead of looking away, she acted.

She saved us.

Two hours later, I sat in the back of an ambulance with Caleb pressed against my side when Detective Lauren Hayes arrived. Her face was grim as she climbed in beside me.

“We have Marcus in custody,” she said. “He’s talking. But there’s more.”
