who collaborates with the Nazis. A 2021 review by Anthony Daniels of Horler's 1944 book Virus X, however, found the book "strongly anti-anti-Semitic," and stated that "[m]any times in the book the Nazis are denounced for their anti-Semitism." Horler also expressed a disapproval of casual sex, especially homosexuality. Horler wrote to the British police demanding a crackdown on what he saw as "the alarming increase in sex perversion" in London, claiming the city's streets were full of male prostitutes. In his fiction, Horler spent a large amount of time emphasising how "virile" and "masculine" his heroes are. One of Horler's characters, the gentleman thief "Nighthawk", only steals jewels from women he sees as sexually immoral, pausing in his work to scrawl the word "Wanton" on their pillowcases. Critical reception Literary reviewers of the time, such Dorothy L. Sayers and Compton Mackenzie, generally gave negative opinions on Horler's fiction. Horler's novels have not been popular since his death. Critics have taken issue with Horler's plots, described by William L. DeAndrea as "unbelievable" (Horler himself claimed to "give old man coincidence's arm a frightful twist") and characters seen as clichéd. David Stafford describes Horler as "among the worst" of British thriller writers. Selected works Horler wrote some 158 novels including: Standish of the Rangeland (1916) Goal!
