next book was published in 1909 and was the final Raffles story, the full-length novel Mr. Justice Raffles; the book was poorly received, with the reviewer for The Observer asking if "Hornung is perhaps a little tired of Raffles", and stating that "it has not the magic or the 'go' of the first Raffles, and there is no good in pretending that it has". During the course of the year he collaborated with Charles Sansom to write a play A Visit From Raffles, which was performed in November that year at the Brixton Empress Theatre, London. Hornung turned away from Raffles thereafter, and in February 1911 published The Camera Fiend, a thriller whose narrator is an asthmatic cricket enthusiast with an ironmaster father, much as Hornung was himself. The story concerned the attempts of a scientist to photograph the soul as it left the body. Hornung followed this up with Fathers of Men (1912) and The Thousandth Woman (1913) before Witching Hill (1913), a collection of eight short stories in which he introduced the characters Uvo Delavoye and the narrator Gillon, whom Rowland considers to be "reincarnations of Raffles and Bunny". Hornung's next work, The Crime Doctor (1914) marked the end of his fictional output. First World War and aftermath Oscar Hornung left Eton College in 1914, intending to enter King's College, Cambridge, later that year. When Britain entered the war against Germany, he volunteered, and was commissioned into the Essex Regiment. He was killed at the Second Battle of Ypres on 6 July 1915, aged 20. Although heartbroken by the loss, Hornung was adamant that some good would come of it and he edited a privately issued collection of Oscar's letters home under the title Trusty and Well Beloved, released in 1916. Around this time he joined an anti-aircraft unit. In either 1916 or 1917 he joined the YMCA and did volunteer work in England for soldiers on leave; in March 1917 he visited France, writing a poem about his experience afterwards—something he had been doing more frequently since Oscar's death—and a collection of his war poetry, Ballad of Ensign Joy, was published later that year. In July 1917 Hornung's poem, "Wooden Crosses", was published in The Times, and in September, "Bond and Free" appeared. Towards the end of the year, he was accepted as a volunteer in a YMCA canteen and library "a short distance behind the Front
