true irish ghost stories

Irish fairy and folklore there were in abundance but there was no book of ghosts.

Suddenly a brilliant thought struck me. I wrote out a letter, stating exactly what I wanted, and what I did not want, and requesting the readers of it either to forward me ghost stories, or else to put me in the way of getting them: this letter was sent to the principal Irish newspapers on October 27, and published on October 29, and following days. On October 30, the first answers reached me. Within a fortnight I had sufficient material to make a book; within a month I had so much material that I could pick and choose -- and more was promised. . . .
