No Caller ID

It was a boring day at work for Dan at his accounting job. Sitting at his desk, he passed the time looking at the pictures Xena sent him. She was tall, dark-skinned and voluptuous. His drab, but well-paid place of employment didn't feel so tortuous knowing that today, Friday, would be of physical and emotional fulfillment.

Then, a call come in.

There was no number, it just read unknown. Dan decided to answer as the only people with those numbers were telemarketers. Dan answered the phone. All he heard was a very loud hiss. "I'm inside the walls."
