Invasion of 1910, which originally appeared in serial form in the Daily Mail newspaper from 19 March 1906, was a huge success. The newspaper's circulation increased greatly, and it made a small fortune for Le Queux, eventually being translated into twenty-seven languages and selling over one million copies in book form. The idea for the novel is alleged to have originated from Field Marshal Earl Roberts, who regularly lectured English schoolboys on the need to prepare for war. He was a member of Legion of Frontiersmen. Le Queux was reportedly less than happy about an abridged German translation (with an altered ending) appeared the same year: Die Invasion von 1910: Einfall der Deutschen in England translated by Traugott Tamm. World War I At the beginning of World War I Le Queux became convinced that the Germans were out to get him for "rumbling their schemes" and requested special protection from German agents, leading to a continual struggle with the Metropolitan Police both at his local Sunbury station and through correspondence with its headquarters at New Scotland Yard. The authorities, however, in the words of Edward Henry (head of the Metropolitan Police) saw him as "not a person to be taken seriously" and saw no need to fulfill his request. Radio work Le Queux was interested in radio communication; he was a member of the Institute of Radio Engineers and carried out some radio experiments in 1924 in Switzerland with Dr. Petit Pierre and Max Amstutz. That same year he was elected the first President of the Hastings, St. Leonard's and District Radio Society, whose inaugural lecture was delivered on 28 April 1924 by John Logie Baird. Le Queux was eager to help Baird with his television experiments but said that all his money was tied up in Switzerland. He did however write an article, Television-a fact which appeared in the Radio Times in April 1924 which praised Baird's efforts. Other work Apart from fiction, Le Queux also wrote extensively on wireless broadcasting, produced various travel works including An Observer in the Near East and several short books on Switzerland, and wrote an unrevealing and often misleading autobiography, Things I Know about Kings, Celebrities and Crooks (1923). The latter contains, among other fantastic stories, the claim by Le Queux that he saw a manuscript in French written by Rasputin stating that Jack the Ripper was a Russian doctor named Alexander Pedachenko
