Sydney Horler (18 July 1888 – 27 October 1954) was a prolific British novelist specialising in thrillers. Born in Leytonstone, Essex, and was educated at Redcliffe School and Colston School in Bristol.
His first job was with Western Daily Press and Allied Newspapers in Bristol started in 1905. This lasted until 1911 when he left to become a special writer on the staff of Edward Hulton and Co. in Manchester. He moved to London to work on the Daily Mail and Daily Citizen in Fleet Street, although he also worked in the propaganda section of Air Intelligence towards the end of the First World War. When it ended he joined the editorial staff of George Newnes as a sub editor of the John O'London's Weekly. He didn't see eye to eye with the editor and after a big row in 1919 his employment was terminated.
He decided to become a full-time writer. He became a popular author with the publication, in 1925, of his first crime novel, The Mystery of No.1, and with novels such as Checkmate (1930). Horler's work was influenced by other popular thriller writers such as Edgar Wallace and "Sapper". His main hero was "Tiger" Standish, a character similar to Sapper's Bulldog Drummond. Horler's work began to be commercially successful after being serialised in the News of the World. By the 1930s, Horler's books had sold an estimated two million copies.
Horler frequently used his work to put forward his opinions. He was a supporter of the British Monarchy and the Church of England (of which he was a member). Horler's works also incorporated his own prejudices. Watson notes both his fiction and non-fiction regularly express negative sentiments about non-English peoples. Horler's heroes, such as Tiger Standish, regularly use derogatory terms like "wogs" and "stinking Italianos", and Horler also expressed contempt for both the Americans and the French in his diaries. Writers such as Bill Pronzini and Malcolm Turnbull have noted that Horler's novels regularly featured negative depictions of Jews as criminals and racketeers, and he made denigrating comments about the Jewish community in his memoirs, Excitement: An Impudent Autobiography. Not even the rise of Nazism made any change to Horler's anti-semitism; Turnbull points out Horler subscribes to "wartime slanders of Jew-Nazi collaboration and Jewish wartime profiteering in his 1940s titles". Horler's book Nighthawk Mops Up (1944) features a Jewish villain, Wilfred Abrahams, who collaborates with the Nazis.
