Mozart and the mysterious stranger, 1791 (c1914). The stranger was a messenger from Count Walsegg-Stuppach with a commission for a Requiem for voices and orchestra. The Requiem was for the Count's wife, Anna, who had died in February 1791 at the age of 20. It was the Count's intention to pass the work off as his own. Mozart died before he could complete the Requiem but it was finished by one of his pupils and duly delivered. From A Day With Wolfgang Amadeus Mozart by May Byron. (London, c1914).
