The disappearance is mysterious and, as a body hasn't been found, it's only natural for people to wonder what else might have happened.
However, hints about her friend, her partner, saving up and hiding out really do suggest that some people have just read too many of these trashy chick lit thrillers that appear everywhere nowadays.
They usually have a picture of a woman or a house on the front cover and end with someone having a double life, someone murdering someone because they want their life or someone hiding a dastardly secret.
This is real life though, not a trashy thriller.
