No one knows what transpired many years ago between Lawrence and his purported guest; the issue still remains secret to this day.
All fine and good. The author may keep secrets from the guests, or from any character in the story. However, the author should never keep secrets from the reader. As it is, the story builds well. Readers are interested, intrigued. In the end, they feel ticked, even cheated, when the author does not tell them what has happened.
This is a good story, but we need more. We need the mystery solved.
Thanks for posting it in the Inkwell.
