Marcus frowned. The voice belonged to a child, perhaps no older than six or seven. His tone softened at once. “Hello there, sweetheart. Why are you calling the police so late? Where are your parents?”

There was a pause, and then the child whispered, “They’re in the bedroom.”

“Can you put your mom or dad on the phone?” Marcus asked gently.

A long silence followed. Then the girl spoke again, even quieter than before. “I can’t.”

Marcus sat up straighter in his chair, unease stirring in his chest. “Tell me what happened. You only call us if something important is going on.”

“It is important,” the girl said, and he could hear her trying not to cry. “I went to wake them up, but they won’t move. They won’t answer me.”

The sleepiness that had dulled Marcus’s mind evaporated in an instant. His instincts screamed that this was no ordinary call.

He kept his voice calm for her sake. “Maybe they’re just sleeping very deeply. It’s very late after all.”

“No,” the girl whispered. “I shook them. They always wake up when I come in. But not this time.”
