I dragged myself forward using my elbows, inch by inch toward the hallway where reception occasionally returned. Evan crawled behind me, trembling but silent. By the time we reached the end of the hall, I had one shaky bar of service.

I dialed 911. The call failed. I tried again. And again. My hands were slick with sweat and weakness.

Finally the call connected. “Emergency services. What is your emergency?”

“My husband poisoned us,” I whispered. “He left, but he might come back.”

The dispatcher’s calm urgency steadied me. “Tell me your address. Are you somewhere you can lock yourself inside?”

“There is a bathroom,” I said. “I think we can reach it.”

I guided Evan with an arm around his waist. He could barely stand. His pupils were huge, swallowing the color from his eyes. When we reached the bathroom, I locked the door and turned the faucet on, letting him sip water slowly.

The dispatcher kept me talking. Asked what we had eaten, when symptoms began, whether I could hear anyone outside.

Then my phone buzzed.

A text from an unknown number:

Check the trash. You will find proof. He is coming back.

My breath caught. Who would know that?
