Something in the mail
At this time of day, she never received mail. However, just as she was about to quit up, she heard her mailbox vibrating. Strange, she observed. She hurried to the front door to see whether somebody had left something there, but no one was visible from the street.
A strange letter
She discovered a note in her mailbox. The person who wrote it had to deliver it because there was no postal stamp personally. This is not possible. She took the letter out of the envelope and began to read it. When she read the letter, she could not believe what she saw.
