"I went in through the side garage door, which Corey said was always open. Ms. Morris's car was parked inside. I hurried to the house door and knocked. No one answered. I knocked again, then tried the knob. The door was locked. Not surprisingly, Corey also knew where they kept the key. I unlocked the door, slipped inside, and called, "Hello?" Silence. "It's, uh, Maya," I said. "Maya Delaney." Like they'd need a last name."
