William Butler Yeats and the Murder of Honor Bright

My family history suddenly came to life. One small fact led to another, until I found out who my grandmother was, and why she had been murdered.
 
 
This book began as a series of short notes, of scribbles about facts from the internet or the library, about feelings, places and situations.
Suddenly there were too many, all collected in covers and boxes - but they were easy to lose or forget. So they were all written into an old schoolbook, and soon chapters of book.
Finally I had to write the story to establish the facts. Why was Honor Bright murdered by the Irish Free State?
