Via Sunday Miscellany on RTÉ Radio 1: an unforgettable phone call with James Joyce's grandson, by Deirdre Mulrooney - listen above.

A 0033 number calling. Could it be...?

I picked up, to hear a deep, raspy male voice declaring "I got a letter! I got a letter!"

"Is that Stephen Joyce?" I said, delighted. "Thank you so much for getting back to me! So you got my letter about my documentary on Lucia Joyce?"

"I am 87 years old! I am 87 years old! Ireland has disgraced herself again!" came the reply.

He sounded furious.

Carefully, I ventured: "How has Ireland disgraced herself?"
