What happened when Hallock down his desk and waited for getting ideas for his ghost story?

When Hallock sat down to write the ghost story, everything was pretty natural. He could think of nothing very ghostly. His mind kept wandering to various things such as his wife and related matter. However, he soon realised that this would lead him to nowhere. In this way he would never be able to get an idea on how to write a ghost story. Then he started staring at the ceiling. He started talking to himself saying: “This writing business is delightful, isn't it?” His behavior has reached such a point of absurdity where he started talking aloud to himself. This is when appeared the ghost of Helen of Troy who said: “Yes...I should say it is!”
