A Secret Signal

"As far as I know, there is a protective net with an alarm system on the high walls of the quarantine zone. If someone gets close, the alarm will automatically call the police. However, there is only one flaw in the system, which is that it malfunctions during rainy days."

Frederic tapped a program on his computer. He looked at the weather forecast for the past two days that there would be heavy rain around four in the afternoon tomorrow. It would continue until eight in the evening.

"Four hours will be enough."

The Quarantine Zone was not big. Robert and Pearl lived in the second row. It was a rainy day, so it was bound to be cloudy. In this way, they could provide cover for them. They planned to let two people go in and one person backs up.

William planned to go in with Frederic, while Elyse drove and backed up them.
