By March 1924, Puccini had completed the opera up to the final duet. However, he was dissatisfied with the text of the final duet, and did not continue until 8 October, when he chose Adami's fourth version of the duet text. Two days later, he was diagnosed with throat cancer. Puccini seems to have had some inkling of the seriousness of his condition: before leaving for Brussels for treatment, he visited Arturo Toscanini and begged him, "Don't let my Turandot die." He died of a heart attack on 29 November 1924.
