It is a stormy night. There is a chess game going on and this in itself can be suspenseful or apprehensive. Read the portion that describes the place and home that they live in. The author sets the scene and the atmosphere around the characters.
Explanation:
This story was written in the early twentieth century and it reads like a Victorian story. There is old fashioned language used and at that time the amount of money they are talking about - was a lot of money. Just reading the portions to set the scene give you a ghost story like presence. Remember too, that the use of a mystical object (supernatural sense) makes you get goosebumps.
