his phone buzzed again. ‎A new message appeared. ‎“I’m behind you.” ‎He slowly turned around… ‎But no one was there. ‎Then suddenly… ‎his phone dropped to the floor. ‎And the last message sent from his number said: ‎“Got him.” ‎The next morning… he was gone. ‎And his phone was still there… ‎with no sign of anyone else.
