Lena called Tessa King.

“I need Incident Command on a recorded line. Tell them Gate Seven’s remote reading is unreliable, the revised operating certificate is disputed, and the west evacuation route needs immediate field verification. I am recommending that they prepare a precautionary evacuation of Willow Court now.”

“How long do we have?” Tessa asked.

Lena looked at the marker outside the window.

“Not enough to wait for a committee.”

Chapter Three: A Siren Nobody Heard

At 4:39 a.m., county emergency management director Elaine Rhodes joined the call. Her voice sounded as though she had spent the past hour speaking into every telephone in the state.

“Mercer, I have Grayline on another line telling me this is a sensor discrepancy, not a flood emergency. The city’s public works director says we could cause a panic. What are you seeing that they aren’t?”

Lena looked at the screen showing green.

“Water, Elaine. A physical marker that predates their equipment, and three readings from three separate people. Grayline is giving you a number from a system we have not independently verified. I have a revised certificate in front of me claiming my approval. I did not approve it.”

A faint scraping sounded over the call. Elaine was writing.

“What do you need?”

“A precautionary evacuation order for Willow Court and the low end of Maple Street. Buses sent to the ridge entrance. A traffic officer at the old mill crossing. Somebody to confirm that the shelter route is actually open. And I need Grayline to release the gate controls to city operators under emergency supervision.”

“Can the gate be closed?”

“I haven’t seen enough to promise that.”

There was another pause.

“That’s a difficult thing to tell a mayor on a Saturday morning,” Elaine said.

“It would be more difficult to tell seventy families why we waited.”

The director took one breath. “Order approved. I’ll call the mayor myself. Get me status every ten minutes. No unsupervised work on that gate.”

Lena glanced at Frank, who nodded and was already reaching for his radio.

For one brief moment, she allowed herself to feel relief.

Then Tessa spoke again.

“Incident Command, we have a problem. West-district warning siren did not activate on the test command.”

Elaine answered immediately. “Try the backup.”

“No response.”

Lena closed her eyes.

The west-district siren sat atop the old volunteer firehouse, three blocks from Willow Court. People there knew its voice. It had sounded for tornado drills, chemical spills, and once when a high school student accidentally triggered the countywide test. An evacuation order could appear on a phone screen, but many residents still listened for that siren. Some did not own smartphones. Some slept with phones turned off. Some assumed any alert without the siren was a mistake.
