Mysterious Phone Calls

A pair of busy parents hired a full-time nanny to care for their child. However, after starting the job, the nanny received strange phone calls for several days. A mysterious male voice on the other end of the line would say, "Someone wants to harm the baby..." before hanging up. The nanny, filled with panic, would rush to the baby's room each time, only to find the baby sleeping peacefully in the crib.

Finally, one day, after the phone call ended, the nanny decided not to check on the baby and acted as though the boy who cried wolf. However, she couldn't bear it any longer, and she called the police. The police worked to trace the caller, and in no time, they provided a response: "Ma'am, the calls from that man... came from inside the house."
