published in 1935. Later that year, Sinclair was fired by the Star after failing to get the story on the outbreak of the Second Italo-Abyssinian War in Ethiopia. The Star reported that Sinclair was leaving journalism to take a job in advertising. The Star wrote that Sinclair had travelled 340,000 miles in 73 countries for the newspaper. At the time, he was working on his fourth book, Khyber Caravan, based on his travels in Afghanistan. Doubts were frequently raised by readers that Sinclair had actually experienced the incidents he reported. His Khyber series was so widely questioned that the Star assigned another reporter to investigate Sinclair's claims. Sinclair's time away from journalism was short-lived. Three months after joining the staff of MacLaren Advertising, Sinclair returned to the Star, this time as a sports columnist. Sinclair was hired shortly after the sudden death of Star sports editor Lou Marsh, who had been one of Canada's best-known sports journalists. According to sportswriter Scott Young, Sinclair's transition to sports was "monumentally unsuccessful." After a year in sports, Sinclair returned to general reporting and late in 1938 he again went on an Asian tour. He remained at home during the Second World War and was not accredited as a war correspondent. CFRB and Front Page Challenge Following the unsuccessful Dieppe Raid in 1942, Sinclair was asked by Red Foster, a news broadcaster at Toronto radio station CFRB, to provide some narration for a broadcast on Canadians at Dieppe. Sinclair ended up writing the story as well as reading it on the air, and continued to contribute brief reports to the station. Several months after he started, his radio work came to the attention of his bosses at the Star, which had a policy prohibiting its reporters from regularly writing reports for other outlets. Once again, Sinclair was fired. In February 1943, he formally joined the CFRB team, becoming part-owner of the station the following year. He would continue to be associated with CFRB for over 40 years until his death. He returned to the Star in 1949, this time as a freelancer, for one final international tour, which included his coverage of the end of the Berlin Blockade. He remained a contributor to the paper, writing a radio and TV column, until December 1962. In 1957, Sinclair also began a career in television, as a panelist on the CBC Television series Front Page Challenge.
