A mystery set in London. An elderly man is murdered and suspicion falls on his young widow. But then things get very complicated and lies and clues abound.

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.
