“Just hold that happy thought, Peter...”

The line went dead, and Detective Peter Files stared blankly at the cement wall. His partner Julie Reilly holstered her weapon and stared at Peter. "AAAAHHHH!!!!" screamed Peter at the top of his lungs as the rotary phone flew into the cement wall - the broken fragments of ancient technology landing in the pool of blood that covered the floor. "This guy is screwing with us," said Peter, more to himself than to Julie. "What are we missing?"

Detective Files began pacing as he waited for the crime scene investigation unit to arrive. His mind was racing, jumping between the 23 murders he has investigated, praying that he finds some connection other than the sadistic signature of - "Just hold that happy thought Peter" at the end of each taunting phone call.
