aroused further suspicions in Britain. Sir Samuel Instone and his brother Theodore offered Matthews a huge salary if he would keep the ray in Britain and demonstrate that it actually worked. Matthews refused again – he did not want to give any proof that the ray worked as he claimed it would. Matthews returned to London 1 June 1924 and gave an interview to the Sunday Express. He claimed that he had a deal with Royer. The press again took his side. The only demonstration Matthews was willing to give was to make a Pathé film The Death Ray to propagate his ideas to his own satisfaction. The device in the movie bore no resemblance to the one government officials had seen. In July 1924, Matthews left for the US to market his invention. When he was offered $25,000 to demonstrate his beam to the Radio World Fair at Madison Square Garden, he again refused and claimed, without foundation, that he was not permitted to demonstrate it outside England. US scientists were not impressed. One Professor Woods offered to stand in front of the death ray device to demonstrate his disbelief. Regardless, when Matthews returned to Britain, he claimed that the USA had bought his ray but refused to say who had done it and for how much. Matthews moved to the US and began to work for Warner Bros. Further inventions In 1925 he invented what he called the "luminaphone". On 24 December 1930 Matthews was back in England with his new creation – a Sky Projector that projected pictures onto clouds. He demonstrated it in Hampstead by projecting an angel, the message "Happy Christmas" and a reportedly "accurate" clock face. He demonstrated it again in New York. This invention was not successful either, and by 1931 he faced bankruptcy. He had used most of his investors' money for living in expensive hotels. In 1934 Matthews had a new set of investors and relocated to Tor Clawdd, Betws, South Wales. He built a fortified laboratory and his own airfield. In 1935 he claimed that he worked on aerial mines and in 1937 that he had invented a system for detecting submarines. In 1938 he married Ganna Walska, a Polish-American opera singer, perfumer and feminist, whose four previous husbands had owned fortunes totalling $125,000,000. In 1935 he became involved with the right-wing Lucy, Lady Houston and intended to carry out
