William Le Queux 
The Seven Secrets [EPUB ebook] 

William Tufnell Le Queux (July 2, 1864 London – October 13, 1927 Knocke, Belgium) was an Anglo-French journalist and writer. He was also a diplomat (honorary consul for San Marino), a traveller (in Europe, the Balkans and North Africa), a flying buff who officiated at the first British air meeting at Doncaster in 1909, and a wireless pioneer who broadcast music from his own station long before radio was generally available; his claims regarding his own abilities and exploits, however, were usually exaggerated.
