Wednesday is a newly famous published writer. Her serial killer, gothic mystery novels that follow Viper De La Muerte, who Wednesday describes as "smart, perceptive, and chronically misunderstood," got to be best sellers with thousands of readers around the world and translated in many languages. Her books are unique because they are written on an antique typewriter. Wednesday didn't care about the fame and its perks, only about her work. She isn't into social media or selling herself, so she's not in contact with her fan base in the traditional way. She lives in a private and secluded country home, away from the society she despises, only with her essentials and without modern and extravagant stuff. Her fans found a way to contact to her by sending handwritten fan mail letters to her, which she always reads but never responds to any.

Every night she dedicated one hour before her sleep to read those letters. There was one that caught her attention. The sender seemed to understand her main character and serial killer Viper De La Muerte as they wrote a very extensive essay about him and his reasons why he murdered his victims. The sender wished to receive an autograph from her which they'd "kill for it" as they wrote. Wednesday was fascinating by this letter, it's like someone actually understood the depth of her character, one thing she noticed it's that the letter was written with typewriter too. That person seemed to be a true fan of hers, so she was tempted to answer back for the first time, but she noticed something weird. The sender was anonymous and the letter didn't had any personal information, like an address, which means it wasn't mailed by the Postal like the others, but someone actually left it at her door.

Wednesday tried to brush it off by opening the next letter but it was still lingering on her mind. Some days after she heard about some concerning news. Someone was recreating her novel's murders. There was actually a "Real Viper De La Muerte" who was wanted by the police for three murders.
