W B Yeats's extra-marital lover,
their illegitimate son,
and her murder.

In 1913 William Butler Yeats studied poetry with Ezra Pound, and from this date all his verse was based on real life.
He was made a Senator in the new Irish Free State in 1922, and received a Nobel Prize for poetry in 1923 - so what caused his sudden depression and despair in 1925?
The poetry he wrote just after his marriage to George reveals his affair with a young Catholic girl and the birth of their illegitimate son. His heartbreak, grief and despair is revealed in the most eloquent love poetry in the English language.
