Mister 13 — Alicia Dean

Psychologist Giselle Bishop is treating a patient who suffers from friggatriskaidekaphobia, a fear of Friday the 13th. When he was younger, his family was murdered on Friday the 13th by an unknown killer dubbed Mister 13 by the media. Since then, he's been terrified to leave his house on the dreaded date. She understands his fear because years earlier, her roommate fell victim to Mister 13.With another Friday the 13th approaching, Giselle convinces him to overcome his fear by facing the very day that paralyzes him, so he reluctantly ventures out. But when she sees a news report that a young woman was found murdered by someone with the same MO as Mister 13, she understands she has made a grave error, and her patient is right to believe he is in danger. But he's not the only one, because now Mister 13 is coming afterher.
