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 consider to be " reincarnations of Raffles and Bunny " . Hornung 's next work , The Crime Doctor ( 1914 ) marked the end of his fictional output .
