And Then There Were None: A Note from Agatha Christie
“I had written this book because it was so difficult to do, and that idea fascinated me. Ten people had to die without it becoming ridiculous or the murderer being obvious. I wrote the book after a tremendous amount of planning, and I was pleased with what I had made of it. It was clear, straightforward, baffling, and yet had a perfectly reasonable explanation; in fact, it had to have an epilogue in order to explain it. It was well received and reviewed, but the person who was really pleased with it was myself, for I knew better than any critic how difficult it had been.”
Agatha Christie, 1939
