Well done, Thomas, who correctly found the answer to my Identify The Author quiz.
Franz Kafka (this is him pictured on the right, not Thomas!) was the famous writer I was looking for.
There were five clues: Berlin, Joseph, Seven, China and Muir.
Berlin - while he was born in Prague, he settled in Berlin.
Joseph - the name of the main character in the novel The Trial.
Seven - the number of works he had published in his lifetime.
China - refers to his selection of shorter fiction printed in 1931: The Great Wall of China.
Muir - refers to Willa and Edwin Muir who translated his work from the German.
Stay tuned for my next literary challenge.
