Question

Why does the narrator say that he didn't specialize in ghost stories but they seem to specialize in him?

Answer 1

The narrator made this comment to convey to the reader that he himself did not know he conceived the entire plot of the ghost stories that he wrote. He just wished to write the story, and then automatically he would receive the inspiration to write the story.

Later on in the chapter we come to know that when he just wished to write the story, asking heaven's help for the plot, a ghost from The Writer's Inspiration Bureau was assigned the task of helping the struggling writers with the story writing.

Hallock himself shuddered to know that it was Helen, the ghost who gave him the inspiration to write ghost stories.
