Alexis is wearing the Shock Collar this morning!

Today's question: Decades ago, a teenager and her friends were stuck inside a house for an entire day while vacationing in Switzerland. There was a terrible storm outside...and to pass the time, the group would read each other ghost stories, then someone suggested they have a competition of their own.... who could write the scariest one!?  

The Seventeen year old girl came up with an idea... told her friends... and the rest is history. Her story NOT ONLY took top honors that day... BUT was published in over 200 countries... and the main character was featured in movies. Tell me which scary character am I talking about?
